Router IP Address for Mac

From Sonora Graphics:

Router IP Address is a small utility for discovering the dynamic IP address assigned by your Internet Service Provider (ISP) when you have a router connecting several computers to a single internet connection (cable modem, DSL, or telephone modem).

Using router IP Address is simplicity itself. Just run the program and it displays the IP address that the rest of the Internet sees when you browse or communicate with various service providers. If you have a direct connection to the Internet this number should match that being used by your operating system but if you are using a router or gateway on your local network it will likely be different.
