Ignoring domain CONFIG_DOMAIN for DHCP host name HOSTNAME

[jockesve]

I get following "DNSMASQ_WARN" errors/warnings daily that are shown on UI:
Warning in dnsmasq core: Ignoring domain for DHCP host name
and the provided documentation link doesn't say that much to me:

"> Ignoring domain CONFIG_DOMAIN for DHCP host name HOSTNAME

A DHCP client is not allowed to claim name HOSTNAME in the current DHCP configuration."

Client is already added to group that is NOT using Pi-hole for DNS.

Is there anything I should/could do to avoid these warnings?
Are these serious?
Please answer in lay-man terms as I am not that skilled in this, just an ordinary user.

See Ignoring domain CONFIG_DOMAIN for DHCP host name HOSTNAME - #8 by DL6ER.

In your case, create /etc/dnsmasq.d/99-domains.conf and add:

domain=XXX.XXXXX.SE,<ip-address>,local

Substitute XXX.XXXXX.SE with your actual domain from the warning, and <ip-address> with the IP of your RS30139079 host.
Run pihole restartdns for those settings to take effect.

TY, I'll try that after work today!
