192.168.100.17 Admin Login

192.168.100.17 is a Class C private IPv4 address belonging to the 192.168.100.0/24 subnet — a range closely associated with cable modems, modem-router combos, and ISP-provisioned broadband gateway devices from manufacturers such as Motorola, ARRIS, Huawei, ZyXEL, and TP-Link. Unlike the more common consumer subnets such as 192.168.1.x or 192.168.0.x, the 192.168.100.x range is predominantly used by ISP-supplied hardware to avoid IP conflicts with customer-owned routers placed downstream. The primary default gateway in this subnet is 192.168.100.1, and 192.168.100.17 is the seventeenth usable host address within the same network. It is most commonly assigned by your router's DHCP server to a connected device — such as a laptop, smartphone, smart TV, gaming console, or IoT device — or manually configured as a static IP for a specific piece of equipment that needs a consistent, predictable address on your local network.

How to Access 192.168.100.17

Because 192.168.100.17 is a host address rather than a typical router gateway, you will not normally reach a router admin login page by typing http://192.168.100.17 into your browser. Instead, this address is assigned to a device connected to your network — for example, a computer, printer, IP camera, or smart home hub. If you have manually configured a device to use 192.168.100.17 as its static IP, you may be able to reach that device's own web interface (if it has one) by entering this address in your browser.

To access your router's admin panel on a network using the 192.168.100.x subnet, you should navigate to 192.168.100.1 instead. This is the default gateway address used by Motorola, ARRIS, Huawei, ZyXEL, and TP-Link devices on this subnet. From there, you can log in with your admin credentials and manage all of your network settings, including DHCP leases, port forwarding, wireless configuration, and security options.

If you are unsure whether 192.168.100.17 is your device's current IP address, you can verify it quickly. On Windows, open the Command Prompt (Start > cmd) and type ipconfig, then press Enter. Look for the IPv4 Address field under your active network adapter. On macOS, go to System Settings > Network > your active connection > Details. On Android or iOS, tap the connected Wi-Fi network in your settings to view the assigned IP address.

What Does It Mean When Your Device Is Assigned 192.168.100.17?

When your device receives the IP address 192.168.100.17, it means your router's DHCP (Dynamic Host Configuration Protocol) server has automatically assigned this address to your device from its available pool. On networks using the 192.168.100.x subnet — typical of Motorola, ARRIS, Huawei, ZyXEL, and TP-Link cable modem-routers — the DHCP pool usually starts at 192.168.100.2 and extends up to 192.168.100.254. Your device being assigned .17 simply means it was the seventeenth device to connect, or the DHCP server selected this address from its available range at the time your device joined the network.

DHCP leases are temporary. Your device may receive a different IP address the next time it connects, unless you configure a DHCP reservation (also called a static DHCP lease) in your router's admin panel. A reservation ties a specific IP address — such as 192.168.100.17 — to your device's MAC address, ensuring it always receives the same address every time it connects. This is especially useful for printers, NAS drives, IP cameras, smart home hubs, and any device you need to reach consistently from other devices on your network.

Router Brands That Use the 192.168.100.x Subnet

The 192.168.100.0/24 subnet is most commonly associated with the following router and modem brands. If your device has been assigned 192.168.100.17, your gateway is likely one of these:

• Motorola — Motorola cable modems and modem-router combos (such as the MG7700 and MB8600 series) frequently use 192.168.100.1 as their default gateway, placing all connected devices in the 192.168.100.x range. If you have a Motorola device and your computer shows 192.168.100.17, your gateway is almost certainly 192.168.100.1.
• ARRIS — ARRIS is one of the most widely deployed cable modem brands in North America, with models such as the SB6141, SB8200, and TG1682G commonly using the 192.168.100.x subnet. ISPs including Comcast/Xfinity, Cox, and Spectrum have provisioned ARRIS hardware that defaults to this range.
• Huawei — Huawei ONT (Optical Network Terminal) fiber gateways and modem-router combos used by ISPs in Asia, Europe, and the Middle East frequently operate in the 192.168.100.x subnet. If your ISP supplied you with a Huawei device and your IP is 192.168.100.17, your admin panel is at 192.168.100.1.
• ZyXEL — ZyXEL DSL and cable gateway devices, particularly those provisioned by ISPs, often use the 192.168.100.x range. ZyXEL modems are common in Europe, Asia-Pacific, and Latin America.
• TP-Link — Certain TP-Link modem-router combo units and ISP-provisioned TP-Link gateways also operate in the 192.168.100.x subnet, assigning addresses like 192.168.100.17 to connected client devices via DHCP.

If your device has been assigned 192.168.100.17 and you are unsure which brand your gateway is, check the label on the bottom or back of your modem or router. The brand name, model number, and often the default gateway IP are printed there.

Setting 192.168.100.17 as a Static IP Address

If you want your device to always use 192.168.100.17 instead of receiving a different address each time it connects, you have two options: configure a static IP directly on the device, or set up a DHCP reservation on your router.

Option 1 — Configure a static IP on your device: Go to your device's network settings and manually enter the following values:

• IP Address: 192.168.100.17
• Subnet Mask: 255.255.255.0
• Default Gateway: 192.168.100.1
• DNS Server: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare), or your ISP's DNS

Before doing this, make sure 192.168.100.17 is not already in use by another device on your network. You can check your router's DHCP client list at 192.168.100.1 to see which addresses are currently assigned.

Option 2 — Set a DHCP reservation on your router: Log in to your router's admin panel at 192.168.100.1, navigate to the DHCP or LAN settings section, and add a reservation that maps your device's MAC address to 192.168.100.17. This way, your device continues to use DHCP but always receives the same address. This method is generally preferred because it keeps your network configuration centralized and avoids potential conflicts.

Troubleshooting 192.168.100.17 on Your Network

If you are experiencing connectivity issues on a device assigned 192.168.100.17, here are the most common causes and how to resolve them on networks using Motorola, ARRIS, Huawei, ZyXEL, or TP-Link gateways:

• IP address conflict: If two devices on your network are both using 192.168.100.17, neither will be able to communicate properly. To resolve this, log in to your router at 192.168.100.1 and check the DHCP client list. Release and renew the IP on the affected device (on Windows: ipconfig /release then ipconfig /renew in Command Prompt), or assign a DHCP reservation to prevent future conflicts.
• Cannot reach the internet: If your device shows 192.168.100.17 but cannot browse the web, verify that your default gateway is correctly set to 192.168.100.1 and that your DNS servers are configured. Try pinging 192.168.100.1 from your device to confirm local connectivity. If the ping fails, the issue is between your device and the router.
• Device not getting 192.168.100.17 consistently: DHCP leases expire and addresses can change. If you need your device to always use 192.168.100.17, set up a DHCP reservation in your router's admin panel at 192.168.100.1.
• Cannot access router admin panel at 192.168.100.17: This is expected — 192.168.100.17 is a host address, not a gateway. Navigate to 192.168.100.1 to reach your router's admin interface.

Factory Reset Procedures for Common Brands in This Subnet

If you have lost access to your router's admin panel and need to restore factory defaults, here are the reset procedures for the brands most commonly associated with the 192.168.100.x subnet:

• Motorola / ARRIS: Locate the small recessed Reset button on the back or bottom of the device. Use a paperclip or pin to press and hold it for 10–15 seconds until the lights flash or the device restarts. After the reset, the gateway returns to 192.168.100.1 with default credentials (usually admin / password or admin / admin).
• Huawei: Press and hold the Reset button on the back of the device for 10 seconds. The device will reboot and restore factory settings. Default login credentials are typically printed on the device label.
• ZyXEL: Hold the Reset button for 10 seconds until the Power LED blinks. The device will restart with factory defaults. Default credentials are usually admin / 1234 or as printed on the label.
• TP-Link: Press and hold the Reset button for 5–10 seconds until all LEDs flash simultaneously. After reboot, the device returns to its factory default settings with credentials printed on the label.

Router Username and Password List

192.168.100.17 in the Context of the 192.168.100.0/24 Subnet

The 192.168.100.0/24 subnet provides 254 usable host addresses, ranging from 192.168.100.1 to 192.168.100.254. The address 192.168.100.0 is reserved as the network address, and 192.168.100.255 is the broadcast address. Within this range, 192.168.100.17 is the seventeenth usable host address — a perfectly valid address for any device on the network, whether assigned by DHCP or configured manually as a static IP.

This subnet is particularly common in cable broadband and fiber deployments, where ISP-provisioned hardware from Motorola, ARRIS, Huawei, ZyXEL, and TP-Link defaults to the 192.168.100.x range. The choice of this subnet by ISPs and manufacturers is deliberate: it avoids overlap with the more common 192.168.1.x and 192.168.0.x ranges used by customer-owned routers, reducing the risk of double-NAT conflicts in bridged or cascaded network setups.

Here are some of the most commonly referenced addresses in the 192.168.100.x subnet and their typical roles:

• 192.168.100.1 — The primary default gateway for this subnet, used by Motorola, ARRIS, Huawei, ZyXEL, and TP-Link devices. This is the address you use to access your router's admin panel.
• 192.168.100.2 through 192.168.100.16 — Typically DHCP-assigned addresses for the first devices that connect to the network.
• 192.168.100.17 — The current address; the seventeenth host in the subnet, commonly assigned by DHCP to a laptop, smartphone, smart TV, or other connected device.
• 192.168.100.18 through 192.168.100.253 — Additional DHCP pool addresses available for other devices on the network.
• 192.168.100.254 — The highest usable host address in the subnet, sometimes used as an alternate gateway by certain devices such as the ARRIS SBX-1000P.

What Is a Private IP Address Like 192.168.100.17?

192.168.100.17 is a private IPv4 address, which means it is only reachable from within your local network and is never routed over the public internet. Private IP addresses are defined by RFC 1918 and fall within three reserved ranges: 10.0.0.0–10.255.255.255, 172.16.0.0–172.31.255.255, and 192.168.0.0–192.168.255.255. The address 192.168.100.17 falls within the third range and is classified as a Class C address.

Your router acts as the boundary between your private network and the public internet. Every device you connect to your router — whether by Wi-Fi or Ethernet — receives a private IP address from the router's DHCP server. These private addresses allow devices on your local network to communicate with each other and with the router. When any of those devices needs to access the internet, the router uses NAT (Network Address Translation) to translate the private IP (such as 192.168.100.17) into your router's single public IP address, which is the address visible to the outside world.

Because 192.168.100.17 is a private address, it can be used on any home or office network without registration or coordination with any authority. However, within your own network, each device must have a unique IP address. If two devices share the same address — for example, if two devices are both configured to use 192.168.100.17 — an IP address conflict will occur, causing connectivity problems for both devices. Your router's DHCP server is designed to prevent this automatically, but conflicts can still occur if you manually assign static IPs without checking what is already in use.

Frequently Asked Questions About 192.168.100.17

Is 192.168.100.17 a router's default gateway?

No. 192.168.100.17 is not typically used as a router's default gateway. The standard default gateway for the 192.168.100.x subnet is 192.168.100.1, which is used by brands such as Motorola, ARRIS, Huawei, ZyXEL, and TP-Link. The address 192.168.100.17 is a host address within the same subnet, most commonly assigned by DHCP to a connected client device such as a laptop, smartphone, printer, or IP camera.

Why has my device been assigned 192.168.100.17?

Your router's DHCP server automatically assigned 192.168.100.17 to your device when it connected to the network. On networks managed by Motorola, ARRIS, Huawei, ZyXEL, or TP-Link gateways using the 192.168.100.x subnet, the DHCP server distributes addresses sequentially or from a configured pool. Your device received .17 because it was available at the time of connection. This address may change the next time you connect unless you configure a DHCP reservation in your router's admin panel at 192.168.100.1.

Can I use 192.168.100.17 as a static IP for my printer or IP camera?

Yes. 192.168.100.17 is a valid static IP address for any device on a network using the 192.168.100.0/24 subnet. To assign it statically, either configure the address directly on the device (with subnet mask 255.255.255.0 and gateway 192.168.100.1) or set up a DHCP reservation in your router's admin panel. Before assigning it, confirm that no other device on your network is already using 192.168.100.17 by checking the DHCP client list in your router's interface at 192.168.100.1.

How do I find my router's admin page if my device is on 192.168.100.17?

If your device has been assigned 192.168.100.17, your router's admin panel is almost certainly at 192.168.100.1. Open your browser and type http://192.168.100.1 into the address bar. You will be prompted to enter your router's username and password. Default credentials for the most common brands in this subnet are: Motorola and ARRIS (admin / password), Huawei (admin / admin or as printed on the label), ZyXEL (admin / 1234), and TP-Link (admin / admin). If the defaults do not work, the credentials may have been changed — in that case, a factory reset will restore them.

What other IP addresses are commonly used in the 192.168.100.x subnet?

The most important addresses in the 192.168.100.0/24 subnet are 192.168.100.1 (the default gateway used by Motorola, ARRIS, Huawei, ZyXEL, and TP-Link), and 192.168.100.254 (used by some ARRIS and ISP-provisioned devices as an alternate gateway). All other addresses from 192.168.100.2 to 192.168.100.253 — including 192.168.100.17 — are available as host addresses for connected devices. Other commonly referenced private gateways outside this subnet include 192.168.1.1, 192.168.0.1, 192.168.1.254, and 10.0.0.1.

Is 192.168.100.17 safe to use on my network?

Yes. As a private RFC 1918 address, 192.168.100.17 is completely safe to use within your local network. It is not accessible from the internet, so it cannot be directly targeted by external attackers. However, you should still ensure your router's admin panel at 192.168.100.1 is secured with a strong, unique password, and that your Wi-Fi network uses WPA2 or WPA3 encryption to prevent unauthorized devices from joining your network and obtaining addresses in the 192.168.100.x range.
