Hello to all,
At first, 192.168.1.1 was created for specific manufacturers of routers, but has become the default for broadband internet modems throughout the world. For a big number of consumers this is best suited, because in case you are focused on the security of your own network system, you can easily change this particular IP.
Using this specific IP address is generally safe, as it is immune to popular Internet threats. If a problem comes about, the IP address is well-documented, and it's easy to find a resolution.
