192.168.1.254 represents a private 32-bit IPv4 address, class C and it is a default ip address for a large number of routers, such as Billion ADSL routers, Thompson ADSL routers, Linksys SRW2024, Westell modems and 3Com routers.
I would like to access the configuration of my Cisco router. I arrived a few days ago with the address 192.168.1.254 but today it no longer works (the page loads without stopping and stop by itself).
192.168.1.254 is a private IP address since it fits into IP range which is reserved from IANA as a private range. 192.168.1.254 is a private IP address because it can only be identified inside the network it is currently working in and not outside of it.
192.168.l.254 private IP address is installed on most of the routers by the manufacturers. Although this address is set by the manufacturer at the factory, it can be changed at any time through administrator console.
Any device on a local network can be set to use it, but only one device on the network should use 192.168.1.254 at a time to avoid address conflicts.
Default username and password is "admin" and can also be changed.
