Iirc you mentioned earlier that your system uses DHCP client to get its
IP address and network configuration?

IME setting rc.conf(5) variables like dns_domain, dns_nameservers etc.
works OK with static IP configured systems, but doesn't work with DHCP
clients. Perhaps because DHCP client is already using resolvconf(8) to
setup /etc/resolv.conf, though I've admittedly not looked into it.

One indicator is an /etc/resolv.conf line like this:

# Generated by resolvconf

If you want to control (some) of your resolv.conf content on a DHCP
client system, you could look into configuring resolvconf, e.g. from
resolvconf.conf(5) there are settings like:

     local_nameservers
     search_domains
     search_domains_append
     name_servers
     name_servers_append

and so on. More details in the man page.
