IPv6 support

[Kevin Keane]

With DNS, you generally only test one of the several IP address - EITHER IPv4 OR IPv6. Worse, if you have multiple IPv4 or multiple IPv6 addresses in a round-robin, then you may not even have control over *which* IP you use; it depends on which one the DNS server happens to hand you.

Somebody who cares about every single IP address generally is monitoring at a very low level where DNS gets in the way instead of being helpful.
