Comment (by cohosh):

 Here's a suggested fix:
 https://github.com/cohosh/snowflake/tree/ticket30434

 I went off of [https://tools.ietf.org/html/rfc4291#section-2.2 RFC4291].
 There's no MUST in there, but a "::" indicates a compressed IPv6 address,
 so I added the restriction that if there are more than 2 fields compressed
 it needs "::" somewhere in the address.

 I also added some additional test cases for the timestamps and more
 compressed addresses to make sure we don't miss anything.
