FYI, the dotted-quad notation is merely for human readability sake
(makes it easier for us to figure out subnets etc. can't wait for IPv6)
Actual IP addresses are processed in their true 32bit value nature
when routers make routing decisions etc etc. When you type in a value
in the URL in your browser, it simply skips all the gethostbyname() calls
and fires off a packet to that actual address.
Fire up a binary calculator and put in the decimal value, then switch
to hexadecimal, seperate out the four alphanumerics, then write them
each in decimal. There is your dotted quad notation.

As others have suggested, the only reason people use URL's like that is
a silly attempt at hiding their address and making it harder for people
to complain to the right authority.
