[Pdns-users] Duplicate SOA while using dig and zone2sql

[Eugene Pefti]

Well, I don't have anything against artifacts of AXFR protocol but what
about improvements that were announced in conjunction with zone2sql that is
supposed to suppress duplicate SOA.

I'm quoting release notes from powerdns documentation:

======================================================================
Improvements: 

zone2sql can now accept - as a filename which causes it to read stdin. This
allows the following to work: dig axfr ds9a.nl | zone2sql --gmysql --zone=-
| mysql pdns, which is a nice way to import a zone. 

zone2sql now ignores duplicate SOA records which are identical - which also
makes the above possible.
======================================================================

'dig' emits two SOA records, which is an artefact of the AXFR protocol,
which terminates an AXFR with a final duplicate SOA record.

Not a lot can be done about this.
