Named tried and failed to query a nameserver at 127.255.255.255. But in
a typical Linux system this address is the broadcast address on the
loopback interface, and I guess DNS cannot use broadcast addresses. It
could be caused by a NS record associatied to a bogus A record
containing this address.

Named tried and failed to query a nameserver at 2001:dc7::1, which is an
IPv6 global address. Does your box have a global IPv6 connectivity,
which is required to communicate with such an address ? It's usually
allright if it doesn't, named will eventually query the next nameserver
with an IPv4 address in the list.
In both cases you may find the "offending" records by digging into named
cache dump if it's fresh enough.
