[Description]

There are two network interfaces on MAAS server.

1. 172.24.0.0/24 : Manage DHCP and DNS
2. 192.168.128.0/24 : Manage DHCP.

Looking to the zone configuration

/etc/bind/maas/zone.maas

As you can see, IP addresses of 192.168.128.0/24 and 172.24.0.0/24 are mixed up.

All the A record has to point 172.24.0.0/24 since DNS service is disabled on interface 192.168.128.0/24. However
entries for 192.168.128.0/24 are still being created.

Can you please retry this on MAAS 1.7.0 and seeing if the issue still manifests itself?

[Andres Rodriguez (andreserl)]

We believe that this issue is no longer present as it was filed against 1.7. As such, I'm marking this as a won't fix.
