World's longest domain name

Some Trivia. I liked the pi value domain name.

BTW, it goes like this:
1) Each domain name can be maximum upto 63 octets. (Octets is 8bits; can safely be considered 1 English Character).
2) The sub-division of domains like (cs.univ.edu;math.univ.edu) can go upto 127 levels.
3) But the entire domain name may not exceed 253 octets.

So, if we are to search for the longest domain name (including sub-domains), we will end up with 253 english character long string. ( That would be like a page of characters). :)
