[ipv6hackers] looking for the best tools to handle 128 bit integers

[Mr. Hinky Dink]

I'm not quite sure how to handle them with C.

Any standard libraries I may have missed?

inet_ntoa() and inet_aton() seem to be stuck in the past, at least
according to the manual pages.

"long long int" is 64 bits and __int128 doesn't seem to exist for me
unless I'm not #including the right headers.
