We need to make sure we normalize the IPv6 addresses when the servers are added. We could either do it with two unsigned BIGINTs (and store them numerically); but the space isn't really a concern and it's convenient to have them easily readable I think; so better to keep storing them like we are now – but normalized ...

Some of the IP related CPAN modules have a "compress IPv6 address" function or method; but I haven't looked too closely at any of them (they all have terrible APIs). Net::IP::XS seemed promising.

@loewis commented on GitHub (Jun 5, 2011):

The standard approach is to use inet_pton for normalization:

use Socket qw(inet_pton inet_ntop AF_INET6);
die inet_ntop(AF_INET6, inet_pton(AF_INET6, '0:1:0:0::2'));

gives 0:1::2
