Obviously a service issue, but just putting it "out there".
At the very least, it might be worth either detecting the type of address and not allowing that to be clickable if it's IPv6 or explaining in appropriate places that lookups on IPv6 addresses will not be successful.
Unless of course there is an alternative service out there that supports IPv6 lookups (I haven't found one yet).
