Title: Help configuring ipv6 in dnsmasq
Post by: marcelogon on July 31, 2025, 04:15:50 AM
I configured IPv4 in dnsmasq and it's working fine. I'm still learning how to use it at home. Can you list the steps to activate IPv6 in dnsmasq? Thank you in advance.

I found this execellently written manual but have not tested it:

Step 5 seems to be optional.
Make sure to remove all ISC and KEA IPv6 configurations and disable their DHCPv6 services before starting to configure Dnsmasq as they would be conflicting.

Also look at https://docs.opnsense.org/manual/dnsmasq.html#dhcpv6-and-router-advertisements, 3rd "Attention" box, if you plan to do dynamic DNS registration.

Hope this helps.
