[Bitcoin-development] Area of Focus

There was recently some discussion around dnsseeds. Currently some
dnsseeds are getting blocked by ISPs because the hosts they pick up
(which run bitcoin core nodes) often run rather web servers alongside
which serve malware or whatever else and thus end up on IP-based malware
blacklists.

Of course we really dont want to move off of DNS because it has this big
built-in anonymity network where the DNS seed servers only get
information about your ISP, not you, and its cached so you dont get as
much information about how many users are making those requests.

A potential solution might be supporting some subdomain which has
results XORed with some constant mask to tweak the real IP.

Additionally, it might be cool to stuff a TXT/AAAA/whatever record with
a signature of the results provided by the DNSseed operator.
