192.168.0.1Configuration:
I know that 127.0.0.1 is the default local loopback, but does 192.168.0.1 have special meaning? Many routers and "default" configurations use that address, but is there some standard that mentions that or is it a de facto standard? Operating System : Microsoft Windows XP Professional

The IP 192.168.0.1 is a non-routable address. Devices come configured with that IP set for security reasons. It can only be routed internally within your own subnet.

The standard that specifies private IP addreses is RFC 1918. Link:
http://www.ietf.org/rfc/rfc1918.txt?number=1918

There are three classes of private IP addresses. Short description about this you can find here: http://www.wikipedia.org/wiki/Private_IP_address

192.168.0.1 is in fact a "routable" address. It's not routable across the internet because no routers will actually route that address as it has been set aside for "private" networking.

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private networks:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

Note that the first block is nothing but a single class A network number, while the second block is a set of 16 contiguous class B network numbers, and the third block is a set of 255 contiguous class C network numbers.
