Tonight, I spent a few hours implementing RFC5952: https://github.com/colmmacc/s2n/commit/4e7d2424b059b1350353fbb95c251d5ff024535e … ... because it turns out that there's no portable way to be sure that IPv6 strings will be in a canonical format. How is that not fixed in 2019? Crazy! Exact-match is needed in many applications.

@andrew729 points out that I might be stretching it with "legally" because the RFC says :: is a "MUST". So these are the 926,834 ways that inet_pton or getaddrinfo will accept the same address. This whole thing started because we saw 0:0:0:0... in an X509 dump.Show this threadThanks. Twitter will use this to make your timeline better. UndoUndo
