192.168.100.10 Admin Login

192.168.100.10 is a private IPv4 address belonging to the 192.168.100.0/24 subnet — the same subnet used by router brands such as Huawei and Motorola as their default gateway range. While the most common default gateway in this subnet is 192.168.100.1, the address 192.168.100.10 is frequently encountered as a DHCP-assigned client IP, a statically configured device address, or even a temporary boot-time address on certain cable modems and fiber ONT units. It falls within the Class C private IP range defined by RFC 1918, making it non-routable on the public internet and exclusively used within local area networks (LANs). Other well-known default gateways you may encounter include 192.168.1.254 and 192.168.8.1.

How to Access 192.168.100.10

To access a device or router admin panel at 192.168.100.10, open your preferred web browser and type http://192.168.100.10 directly into the address bar — do not use the search bar. Press Enter and you should be presented with a login prompt. From there, enter your router's username and password. If you haven't changed these, try the most common default combinations: admin / admin, admin / password, or admin / (blank). You can also find the default credentials printed on the label on the back or bottom of your device.

Keep in mind that 192.168.100.10 is only reachable if your computer or device is connected to the same local network — either via Wi-Fi or an Ethernet cable. Because this is a private IPv4 address, it is not accessible from outside your home or office network. If you're trying to reach a device at this address and the page doesn't load, verify that your network gateway is indeed in the 192.168.100.x range before proceeding.

Router Brands Associated with the 192.168.100.x Subnet

While 192.168.100.10 itself is not a widely published factory-default gateway IP, it sits within the 192.168.100.0/24 subnet that is actively used by several well-known networking brands. Understanding which brands operate in this subnet helps you identify your device and troubleshoot more effectively.

• Huawei — Huawei's fiber ONT (Optical Network Terminal) modems and home gateway routers, such as the HG8245H and HG659 series, commonly use 192.168.100.1 as their default gateway. When DHCP is active, connected devices are assigned addresses starting from 192.168.100.2 upward — meaning 192.168.100.10 is a typical DHCP lease address on a Huawei-managed network. The admin panel is accessible at http://192.168.100.1 with default credentials of admin / admin.
• Motorola — Several Motorola cable modem/router combos (such as the MG7700, MB8600, and MR2600 series) operate within the 192.168.100.x subnet. Motorola devices have been observed using 192.168.100.1 as their gateway, and during boot cycles, some units temporarily appear at 192.168.100.10 before settling on their configured address. The default password for Motorola modems is typically motorola with the username admin.
• Arris — Arris cable modems and gateways (widely deployed by ISPs) also operate in the 192.168.100.x range. Arris devices are commonly found with a gateway of 192.168.100.1, and client devices on those networks receive addresses like 192.168.100.10 via DHCP.
• Thomson — Thomson routers and DSL gateways list 192.168.100.1 as one of their known default gateway addresses, placing 192.168.100.10 squarely within their typical DHCP lease pool.

If You Can't Access 192.168.100.10

If typing http://192.168.100.10 into your browser returns an error or a blank page, there are several things you should check before assuming the address is wrong:

1. Confirm your network gateway: Open the Command Prompt on Windows (Start > type cmd > Enter) and run ipconfig /all. Look for the Default Gateway field. If it shows something other than an address in the 192.168.100.x range, then 192.168.100.10 is not on your current network. On macOS or Linux, run netstat -nr | grep default in the Terminal.
2. Check your connection: Make sure your device is connected to the correct Wi-Fi network or plugged in via Ethernet. Accessing 192.168.100.10 from a different network will always fail.
3. Try HTTP instead of HTTPS: Some older routers and modems do not support HTTPS. Make sure you're using http://192.168.100.10 and not https://192.168.100.10.
4. Disable VPN or proxy: If you're running a VPN or proxy service, it may redirect or block access to local private IP addresses. Temporarily disable it and try again.
5. Ping the address: Open Command Prompt and type ping 192.168.100.10. If you receive replies, the device is online and reachable — the issue may be browser-related. If the ping times out, the device may be offline or on a different subnet.

If none of these steps resolve the issue, check our guide to find your router IP address for a full walkthrough.

Changing Your Router's Password on a 192.168.100.x Network

If your network gateway is in the 192.168.100.x range — as is common with Huawei, Motorola, Arris, and Thomson devices — you should always change the default admin password as soon as possible. Default credentials are publicly known and leave your network vulnerable to unauthorized access.

To change your password, log in to your router's admin panel (typically at 192.168.100.1) and navigate to the Administration, System Tools, or Security section depending on your brand. Look for a Change Password or Account Management option. You'll be asked to enter your current password and then type your new password twice for confirmation. Choose a strong password that combines uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable information like your address or birthday.

On Huawei ONT devices, the password change option is found under System Tools → Account Management. On Motorola cable modem/routers, navigate to Basic → Login Settings after logging in at the gateway address.

Factory Reset Procedures for 192.168.100.x Devices

If you've forgotten your admin credentials or can no longer access your router's panel, a factory reset will restore all settings — including the default IP address and login credentials. Below are the reset procedures for the brands most commonly associated with the 192.168.100.x subnet:

Huawei ONT / Fiber Modem Reset

To factory reset a Huawei router or ONT device (such as the HG8245H or HG659):

1. Make sure the device is powered on.
2. Locate the small RESET button on the back of the unit — it is recessed and requires a pin, paperclip, or needle to press.
3. Press and hold the RESET button for 15–20 seconds until the indicator lights flash or change pattern.
4. Release the button and wait for the device to fully reboot (approximately 1–2 minutes).
5. Once rebooted, the device will return to its factory default settings, including the gateway address 192.168.100.1 and default credentials (admin / admin).

Note: On some Huawei ONT models, you can also perform a soft reset via the admin panel under System Tools → Restore Defaults.

Motorola Cable Modem/Router Reset

To factory reset a Motorola cable modem or gateway (such as the MG8702, MB8600, or MR2600):

1. Ensure the unit is powered on.
2. Disconnect the coaxial cable from the back of the modem.
3. Locate the RESET hole on the back of the device.
4. Insert a pin or paperclip and press and hold for 25–30 seconds.
5. Release and wait for the unit to reboot — you'll see the front panel lights cycle through their startup sequence.
6. Reconnect the coaxial cable once the device has fully restarted.

Arris Gateway Reset

For Arris cable gateways operating in the 192.168.100.x subnet:

1. Power on the device.
2. Find the RESET button (usually on the rear panel).
3. Press and hold for 10–15 seconds using a pin or paperclip.
4. Release and allow the device to reboot fully before attempting to reconnect.

What Is 192.168.100.10 and How Is It Used?

192.168.100.10 is a Class C private IPv4 address in the 192.168.100.0/24 subnet. As defined by RFC 1918, addresses in the 192.168.x.x range are reserved exclusively for private network use and are never routed over the public internet. This means 192.168.100.10 can exist on millions of different private networks simultaneously without any conflict — because it is always isolated within its own local network.

In practice, you'll encounter 192.168.100.10 in several common scenarios:

• DHCP-assigned client address: When a router with a gateway of 192.168.100.1 (such as a Huawei ONT or Motorola cable modem) assigns IP addresses to connected devices, 192.168.100.10 is one of the first addresses in the typical DHCP pool. Your laptop, smartphone, or smart TV may receive this address automatically when connecting to such a network.
• Statically assigned device IP: Network administrators often assign 192.168.100.10 as a fixed (static) IP to a specific device — such as a network printer, IP camera, NAS drive, or managed switch — to ensure it always has the same address for easy access.
• Cable modem temporary address: As noted in Netgear community discussions, some cable modems temporarily use 192.168.100.10 during their boot sequence before settling on their configured gateway address of 192.168.100.1.
• Secondary router or access point: In networks where 192.168.100.1 is the primary gateway, a secondary router or wireless access point may be manually configured at 192.168.100.10 to avoid conflicts while remaining on the same subnet.

The full 192.168.100.0/24 subnet provides 254 usable host addresses, ranging from 192.168.100.1 to 192.168.100.254. This gives network administrators ample room to assign addresses to all devices on a home or small office network.

Frequently Asked Questions About 192.168.100.10

Is 192.168.100.10 a router's default gateway address?

Not typically. While 192.168.100.10 is a valid private IP address in the 192.168.100.x subnet, it is not a widely published factory-default gateway. The most common default gateway in this subnet is 192.168.100.1, used by brands like Huawei and Motorola. However, 192.168.100.10 may be configured as a gateway on a custom network, or it may be the address of a secondary device such as an access point or managed switch on a network where 192.168.100.1 is the primary router.

Why does my device show 192.168.100.10 as its IP address?

If your device has been assigned 192.168.100.10, it means your router's DHCP server — likely a Huawei ONT, Motorola cable modem, or Arris gateway with a gateway of 192.168.100.1 — has automatically leased this address to your device. It is one of the first addresses in the typical DHCP pool for the 192.168.100.0/24 subnet. You can keep this address as-is or assign it as a static IP if you need the device to always use the same address.

Can two devices on my network both use 192.168.100.10?

No. Within a single local network, only one device can use 192.168.100.10 at a time. If two devices are assigned the same IP address, an IP address conflict will occur, causing connectivity issues for both devices. Your router's DHCP server is designed to prevent this automatically, but conflicts can arise if you manually assign static IPs without checking what's already in use. Use your router's admin panel (at 192.168.100.1) to view the DHCP lease table and avoid conflicts.

How do I set 192.168.100.10 as a static IP on my device?

To assign 192.168.100.10 as a static IP, you can either configure it directly on the device (via network adapter settings on Windows, macOS, or Linux) or use your router's DHCP reservation feature to permanently bind the address to a specific device's MAC address. The second method is preferred as it keeps all IP management centralized in your router's admin panel at 192.168.100.1. Make sure to also set the correct subnet mask (255.255.255.0), default gateway (192.168.100.1), and DNS server when configuring a static IP.

What is the subnet mask for 192.168.100.10?

The standard subnet mask for the 192.168.100.0/24 network is 255.255.255.0. This means the network portion of the address is 192.168.100, and the host portion is .10. The usable host range in this subnet runs from 192.168.100.1 to 192.168.100.254, providing 254 possible device addresses. The network address is 192.168.100.0 and the broadcast address is 192.168.100.255.

Is 192.168.100.10 safe to use on my network?

Yes, 192.168.100.10 is a completely safe private IP address. Because it belongs to the RFC 1918 private address space, it is never exposed to the public internet and cannot be directly accessed by anyone outside your local network. However, you should always ensure your router's admin panel (at 192.168.100.1) is protected with a strong, unique password — especially if your router is a Huawei or Motorola device that ships with well-known default credentials.
