Description Philipp Hahn

2013-11-06 12:49:38 CET

After adding a IPv6 address to my master, the SOA generation counter was not updated, while the AAAA was still added. This breaks the zone transfer to the proxy, which still uses the old version and does not update its zone.
Updating the host entry in the forward zone updates the SOA counter, so it looks like a bug in the computer module.
