this still does not match `BC:24:11:0` as we recommend in our docs as
this regex requires the fourth octet to also be complete and not just a
nible. you could do something like this:

```
/^[a-f0-9][02468ace](?::[a-f0-9]{2}){0,2}(?::[a-f0-9]{0,2})?:?$/i
```

this would allow the last octet to be incomplete too, but i wonder if at
that point we want to generally allow longer prefixes and just make sure
that a prefix address is not a) a multicast prefix b) a broadcast prefix
and c) a complete set of 6 octets. that may be simpler and more future
proof?
