192.168.0.1 is the most common ip address allocated to new routers, along with its close cousin 192.168.1.1 it is often the gateway address allocated also.
A system called DHCP that runs on a router gives out ip addresses to computers attached to the router. The addresses may start at any address greater than 192.168.0.1 but often will be allocated from a greater number such as 192.168.0.10.
What follows are a few 'practical networking tips' for you to try. You really can't break much by pinging and doing a simple ipconfig on your own home network, so ping away!
To access a router type 192.168.0.1 into your browser or explorer address bar. On some it may be http://192.168.0.1
You may well be ased for a username and password, common variations are as follows

This is used when DHCP is being run and you want to give a new address because of a maybe a conflict or other reason.

Go on give it a go if you like! The IPCONFIG command is great as it tells you some useful things such as what IP addess you have been allocated on the client computer and also the gateway address if any.
The IP addesses we have been referring to here are called IPv4 addresses and are usually written in dot-decimal notation, which consists of the four octets of the address expressed in decimal and separated by periods (octet means eight bits) = 1 + 2 + 4 + 8 +16 + 32 + 64 + 128 = 255 max
