What is a common default gateway IP address for accessing a router's settings?

The choice of 192.168.0.1 or 192.168.1.1 as common default gateway IP addresses is based on their widespread use in consumer-grade routers and local area networks (LANs). These IP addresses fall within the private IP address range designated for personal networks, allowing users to access their router's configuration settings through a web browser.

Typically, manufacturers set these IPs as defaults because they are easy to remember and do not conflict with public IP address space. When setting up a home network, users usually connect to the router using one of these addresses to configure network settings, such as Wi-Fi credentials and security options.

The other choices, while valid IP addresses, are less commonly used for accessing typical home or small office routers. For example, 10.0.0.1 is often associated with larger corporate networks, and 172.16.0.1 is part of another private address range used in more specialized networking scenarios. The IP address 255.255.255.0 is not a valid gateway address; it is actually a subnet mask used to define the network and host portions of an IP address, rather than to access router settings directly.
