Allow me first to set the scene.
We used to use Bind9, but ditched it in favour of PowerDNS, because, frankly, Bind sucks.
We have a "primary" zone in our DNS master. london.wibblesplat.com
There's other zones too, oob.london.wibblesplat.com
The majority of addresses in the non-oob zone are in the range 192.168.0.0/16. The IP of the dns-1 server is 192.168.123.140. (I'm not sure if this is relevant).
I wanted to add some out-of-band (oob) access IPs to the oob.london.wibblesplat.com zone in the range 172.16.254.0/24
This is what's in the database that drives powerdns.
powerdns=# select * from records where name like '%switch%';
id | domain_id | name | type | content | ttl | prio | change_date | ordername | auth

Why is PowerDNS not serving the record? It exists. The query should be fine. Is there something weird about zones not being served if the A record isn't in the subnet the server has access to? (I can't see this being right, what if I wanted (for whatever reason) to re-publish an A record for 8.8.8.8 or whatever).
Any thoughts?
EDIT:
The plot thickens. Out of interest, I nuked the old records, and added some new, shorter ones.
powerdns=# select * from records where name like '%rc1sw%' or content like '%rc1sw%';
id | domain_id | name | type | content | ttl | prio | change_date | ordername | auth

And now.. tom.oconnor@charcoal-black:~$ dig rc1sw1 +search

And it works.
Seems Powerdns might not like so many - characters in a Name. I'll bear that in mind, and carry on. Still, an answer might be nice.
OK, it's the -A1 it doesn't like.
Have a look at this.
powerdns=# select * from records order by id desc limit 5;
