Since others have gotten to the "get me back to IPv4" part of this question, I'll tackle the other bit. I can't say I've seen many ipv6 addresses in the wild, so "look normal" ? uh... let's google, shall we?
Here's a nice link on "normal" IPv6 addresses:
IPv6 addresses consist of eight hexadecimal groups. Each
hexadecimal group, separated by a colon (:), consists of
a 16-bit hexadecimal value. The following is an example
of the IPv6 format:
..and from What Does an IPv6 Address Look Like?:
Colons separate 16-bit fields. Leading zeros can be omitted
in each field as can be seen above where the field :0003: is
written :3:. In addition, a double colon (::) can be used
once in an address to replace multiple fields of zeros. For
can be written
So your example is this:
According to A Dwarf, the %9 is a "zone index", "an identifier that helps transmitting packets across link-local addresses (when a host has more than one interface)". So it's identifying the interface (NIC) received this packet, but not actually part of the IPv6 address.
The "::" means :0:, or :0:0:, or maybe more zeroes. We don't know how many. If we discard the %9, then we're looking at:
Since we know there's 8 groups of 4 hex digits, and we see only 5 groups above, we know there are three groups that the "::" needs to fill. So the actual address is:
