Do you know? The home broadband router has two IP addresses. One is its own private address on the LAN, the other is a public IP address used on the Internet. It can be connected to a home computer through a private IP address and to an external network through a public IP address.
How to find the public IP address of the router
When a router connects to the Internet through a modem, the ISP assigns a public IP address to the router. This address can be found on professional IP address query websites or in the router itself.
All routers have this feature, but in Linksys routers, you can see the public IP address on the status page. The NETGEAR router may call this address the Internet port IP address. You can find it in Maintenance > Router Status screen.
How to find the router's local IP address
The home router sets its local address to the default private IP address. Typically, routers of the same brand have the same IP address, which can be seen in the manufacturer's documentation.
You can also find this IP address in the settings of the router. For example, most Linksys routers display IP addresses like this, Setup > Basic Setup Screen. NETGEAR routers find IP addresses by Maintenance > Router Status page.
Below are some of the most popular router brand's default management IP addresses:
- Linksys routers usually use 192.168.1.1 as the default management address.
- The management addresses of D-Link and NETGEAR routers are usually set to 192.168.0.1.
- CISCO routers usually use 192.168.10.2, 192.168.1.254 or 192.168.1.1.
- Some Belkin and SMC routers use 192.168.2.1.
- HUAWEI routers use 192.168.100.1.
- U.S. Robotics routers use 192.168.123.254.
If you are an administrator, you can change the IP address in the process of router installation. After installation, you can also modify it in the console of the router. Other IP addresses in the home network often change, but the router's private IP address remains unchanged unless it is manually changed.
More information about IP addresses
The router's public IP address changes periodically because the ISP assigns dynamic addresses to most customers. Over time, the dynamic address changes once, maybe for a few hours, maybe a day. We usually say that the IP address is an IPv4 address, and the new IPv6 uses a different number arrangement, but implements similar functions.
