[dns-operations] Minimalistic DNS server for SOA and AXFR

[Jan-Piet Mens]

> Actually named does do SOA queries over TCP before AXFR.

Zone transfer from BIND 9.9.1 to BIND 9.9.1; logs on master:

 view internal: query: ww.mens.de IN SOA -E (192.168.1.20)
 view internal: query: ww.mens.de IN IXFR -T (192.168.1.20)
 view internal: transfer of 'ww.mens.de/IN': AXFR-style IXFR started
 view internal: transfer of 'ww.mens.de/IN': AXFR-style IXFR ended

That initial SOA query looks to me as though its on UDP.
