Replacing dnsmasq with unbound+odhcpd

I'm trying to replace dnsmasq with unbound and odhcpd.
I followed the steps from here:

It works for the most part but some things aren't working.

  1. Static DHCP Leases, static ip is given out correctly but the configured hostname is not used
  2. DHCP leases disappear from luci status overview page
  3. local domain resolution only works on the router and not on the clients

Someone has an idea?

// edit
When i run the netalyzr app from
The app telling the ipv6 server can't handle packet larger then 1280 bytes.
I guess because of the edns_size option.
However for ipv6 no errors are reported.
Also ipv6 reverse lookups don't work. But i had this problem also with dnsmasq.
I'm not sure if this a bug in the app or a problem with my setup.

3. I had to add local domain name on the clients as additionally search domain either in GUI or resolv.conf / dhcp.conf

Thanks for your input.

Local domain name resolution suddenly started to work after some time.
I don't know why.
However i switched over to the following setup:
unbound as main dns server + dnsmasq for local domain name resolution + dhcpv4
Because dnsmasq seems better integrated into luci.

Now i have a different problem with uhttpd.
It doesn't bind to the specific ipv6 address at startup.
I have to restart it manually to make it work.

Dnsmasq treats static IP like preassigned leases and attached clients generate a lease entry with infinite duration. Odhcpd may be assuming it isnt technically a lease and not create an entry. This depends on if the host solicits, renews, or confirms its IP. Unbound scripts will pick up what odhcpd writes in the lease file.
