KEA DHCP missing "Register DHCP leases in DNS Resolver..."

@mdima not sure why the forwarder is still around to be honest, unbound was added and made the default years and years ago - you would think the forwarder would have dropped off by now. But the one thing I do know the forwarder still has a feature that I do not believe you can do with unbound is parallel. or sequential queries. Some users might want to ask all the nameservers at once and just use the first answer.. I do not believe unbound does that.

They might have kept it around because of the long standing problem with dhcp registrations in unbound causing restart of the service which can be problematic.. Now that they are fixing that aspect - maybe forwarder drops off at some point of being included?? I don't believe the forwarder had that problem?

I personally don't understand why with the ability to resolve users don't do that - but there are some cases where resolving has issues.. If you are on a really high latency connection, resolving can be problematic - but unbound can forward..

@herbcso said in KEA DHCP missing "Register DHCP leases in DNS Resolver...":

So based on the 2.8.0 release notes it sounds to me like KEA should now support resolving DNS names, right?

Oh finally! Thanks @herbcso for the tip. Just upgraded to 2.8.0, and now DHCP registration is working properly (including static mappings).

No need for a bunch of ugly Host Overrides on DNS Server anymore!

I'm using KEA DHCP and the "DHCP Registration" field is not present. I'm on 2.8.0. Per this post it should be in latter releases, which 2.8.0 is. Is there something else that I need to turn on?

@guiambros Hi, I just upgraded to 2.8.0 and Register DHCP leases in DNS Resolver, and the static mapping option are not present. Did you have to do anything specific to get these to show up?

@rocdiva Are you sure you're looking in the right service? The DHCP registration option is set in Services / DHCP Server, but your screenshot shows the DNS Server config. Here:

Thank you for pointing that out.
