well, you dont really need that. if your looking to actually type in your own ip then just type:

192.168.0.1 or
192.0.0.1 or
192.0.0.3

a subnet is usally:

255.255.255.0

but... when configuring the browser, just set it on 'easy' and it connects to the DNS server closest too ya (the router... not the server... sorry). It auto-obtains the IP address.
