:: is really an IPv6 address?
Lol. Was gonna ask the same question
According to the tool mentioned in the explanation (http://www.intermapper.com/ipv6validator) all six of those IPv6 addresses are valid.
I think it’s B,D,E,F. Last 3 are global unicast (Anything starts with 2 or 3 with exceptions) and B is IPv4-Mapped; :: is used as source only in some cases not a valid address.
