Net-DNS-SEC updates, seems that IETF has been busy redefining DNSSEC.
When parsing resolver configuration files, IPv6 addresses are now skipped,
as Net::DNS does not yet have IPv6 support.
Broke Net::DNS::Resolver into seperate classes. Many of the globals in
Net::DNS::Resolver no longer exist. They were never documented
so you never used them.... right?
Options to Net::DNS::Resolver->new() are now supported, including
using your own configuration file.
Moved next_id() from Resolver.pm to Header.pm (which is where it is
used).
Tie::DNSHash removed from the package, see Tie::DNS from CPAN for a more
complete implementation of a DNS hash.
Applied David Carmean's patch for handling more than one string in a
TXT RR's RDATA section.
Applied patch from Dan Sully (daniel@electricrain.com) allowing multiple
questions to be part of a DNS packet.
