Does someone has a working recipe for individual domains per vlan? Like VLAN 1 gets
vlan1.home.arpa and VLAN 2 gets
vlan2.home.arpa? My search engine usage skills do not reveal any useful results.
I'm looking for details on where, what, and how I should set in

I have a somehow working setup but this is rather cumberstone, and still has issues with PTR for DHCPv6 assignments from
And I'm still not sure if I'm holding it wrong, or if I have found a config generation bug, present in 21.03 and 22.03, but on 22.03 it causes
dnsmasq to crash.
Important: do not set a general local domain!!!
Instead: define a local domain per interface via a dhcp-option like this:
config dhcp 'lan'
option interface 'lan'
option start '200'
option limit '50'
option leasetime '2h'
list dhcp_option 'option:domain-name,"home.lan"'
This is working on an IPv4-only system. Don't know, whether it's working with IPv6.
My clients get via DHCP and DHCPv6 the DHCP(v6) Option for their domain-name, so the client is aware of its own FQDN and search-domains works, too.
But AFAIK this alone does not solve the issue of having "proper" PTR served by
You need to have

Like I've written, even my somehow glued together config works for IPv4 and IPv6, except for IPv6 GUA addresses out of
I do really like links without any explanation...
/s, but do you want to say I need individual
dnsmasq instances in
/etc/config/dhcp and can not do it with a single one?
Edit: And does this solve my issue that everything is working except IPv6 GUA?
I believe the word you were looking for is thanks, since your searching skills didn't reveal that.
I don't see how dnsmasq can distinguish them.
Works fine for my setup with 3 interfaces however.
AFAIK the client uses the dhcp-option domain-name just for feeding its /etc/resolv.conf (creating a search option). I think, it does not generate any PTR data on the router. Perhaps somebody else can jump in.
Because https://thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html indicates that its a totally valid use-case having multiple domains in
--local=/home.arpa/vlan1.home.arpa/vlan2.home.arpa/ and having set
--domain multiple times, too within a single config for a single process.
From what I have tried you cannot define the
option domain multiple times in uci, or the last entry will prevail.
If you try with
list domain it is not recognized.
