RFC 5782 says that a live DNSxL does list 127.0.0.2 to show that it's
alive, and does not list 127.0.0.1 to show that it's not wildcarded.
We published that in 2010 but it was in draft form for quite a while
before that. For IPv6 BLs, you list ::ffff:127.0.0.2 and don't list
::ffff:127.0.0.1. For name BLs, you list TEST and don't list INVALID.
You can't make everyone follow the rules, but I have to say that it's
been a while since I've seen a BL that I care about that doesn't.
And conversely, if a DNSBL can't be bothered to follow simple standards
or doesn't have the technical competence to avoid listing 127.0.0.1, is
it worth caring about?
If a DNSBL lists an IP in a forest and nobody ever queries it, does
anyone but NANAE care?
