Blog entries describing resolution bugs fixed in Deadwood.

Bugs because of incomplete RFC compliance:

* Long truncated packets:

* DNAME records (no blog posting, fixed August 4; packets are a CNAME packet
  but the DNAME record precedes the CNAME records, and has to be ignored)

* Incorrect handling of upper/lower case:

Bugs caused by broken DNS servers on the 'net:

* Aplus.net's crappy DNS servers (NXDOMAIN, SOA record in NS section, but it's
  really a CNAME):

* Chase bank gives us broken packets when we ask for an AAAA record:

  (The packets are blank DNS packets with no error code instead of a proper
   "not there" reply)

* ibnlive.in.com has one DNS server give us an empty packet along with a
  "SERVER FAIL" RCODE; we have to treat this particular type of empty
  DNS packet like a non-reply:
