There's a lot of buzz on the Internet about this number:
One guy said it's an IPv6 address on his network. Another guy used it as an encryption key in a short little program he published on Slashdot. Someone else pointed out that if anyone attempted to decrypt his program they might be in violation of the DMCA. (There's a lot of vitriol aimed at the DMCA and DRM and AACS and the RIAA and MPAA on the Slashdot site -- something about these things being anti-consumer.) There is an amazing number of references to this number in various forms all over the Internet.
I find it all rather interesting.
