Until you then need to support this syntax: 2001::10.2.2.191

'.' might be a good separator, but for the vast variety of writing
addresses which IPv6 supports ... and that it is a different protocol from
IPv4, I'm glad the separator is different.  ':' might not be ideal, but I
find it a lot better than a lot of other alternatives.

Anyway, the standard is settled, and it has been available for over 15
years ... it's too late to change it in IPv6.
