KEA vs ISC dhcp

[jata]

I am on latest 24.7 and have tried switching to KEA dhcp (I only use ipv4 on my system) but have found that a number of clients do not resolve to their hostname using KEA so I went back to ISC.

Is this a known limitation for KEA dhcp at the moment?

I also remember reading a release note for opnsense 24.7 relating to ISC dhcp and static dhcp reservations - something about having to restart a service after changing/adding reservations. At the moment I need to restart opnsense for these new reservations to apply but there must be a way to do this without having to restart?

You restart DNS, not OPNsense.

Both work

I will clarify "restart it" then.

haha - thanks guys. I knew there was a better way than restarting my router. I tried restarting dhcp but this wasn't working.

To be clear - i restart unbound dns. Correct?

[franco]

Correct.

Any thoughts on my first question regarding KEA and how it handles hostname vs. ISC?

My understanding is that ISC will be around for a while so it's not an immediate concern. I'd be interested to hear if/how others are getting on with KEA?

Dynamic lease registration in DNS is not supported with Kea. Only static leases.

For this is a good reason to have roll your own DHCP server.

Mid-term the idea here is to really take a different path and add DHCP support to Dnsmasq to do dynamic lease registration out of the box. Talk about how stoked we all are about Kea, but some good can come out of this.

That is great news.... Support in dnsmasq.

dnsmasq is lightweight, highly configurable... has been around for so long, so lots of help/ support available on public forums.
I would use dnsmasq over anything for a lightweight resolver.

[franco]

I can't resist: strictly speaking Dnsmasq is not a resolver.

..stubby coming into play?

[franco]

Or bounce through Unbound. It will likely remain the default for that resolver/forwarder discussion's sake.
