Your post below is excellent....thanks.

Using "." or ":" makes sense because these are already in use for ip
and other addresses. It has also become a kind-of tradition that ":" 
separates parts of the numbers when they are written in hexadecimal 
where as "." separates when parts are written as decimal.

Also that we separate 32-bit number into several parts in writing does
not mean somebody else can not write and use the same number as full
32-bit [unsigned] integer. In fact as many of you probably know you can 
use use full 32-bit number as IPv4 address, for example just for fun
try "ping 3231054855" from your dos/unix prompt and then also try
"http://3231054855" at the browser and see where it gets you :)
