How to work out what the ip of the domain dc

NethServer Version: NS8
Module: Domains and Users
On the user interface I have no record of what the dc ip address of the domain is. I wish to create a dns record in pfsense. I can connect to my ad.xxx.xx.xxx internal domain with krb5 kinit but seem to be hitting a wall when trying to pull user information with id in Ubuntu, I may have to throw away NS8 after 30+ hours work migrating if I can’t sort this simple issue.

Is the DNS ip address the same as the main cluster ip address? I’m used to Nethserver 7 which ran the dc in another container and got a separate ip address from the local network.

Thanks
