[Asrg] Another dnsbl draft, now standards flavored

My take:

Think of DNSxL as an exercise in steganography: A few bits of 
information are encoded into something that looks an awful lot like an 
IP address and can be carried over a channel intended to transmit IP 
addresses. Otherwise it's an opaque value.

The choice of 127.0.0.0/8 and ANY sort of range in the IPv6 address 
space is truly irrelevant. These are not IP addresses; they just look 
like IP addresses.
