I have been trying to install FreeIPA with integrated dns i found installing freeipa easy without dns but anything todo with the dns portion of it exceeding complicated. I have a internel dns server that i have been using to store all the host names of my internel pcs and then for anything externel it would forward to another dns server. As far as i can tell the freeipa integrated dns is would replace this and would store all the records needed for freeipa also as far as i can tell it would automatically create the A records and AAAA records for the client pcs added to the domain and keep them updated.

I originally tried making the integrated dns handle the root zone i think that is what its called where it could create records for any subdomains I read online that this wasnt a good idea and also seemed extremely hard todo trying this would end up in a zone overlap error. I think I need to make my registrar point to the integrated dns for this to work.

I read some guides and it seems that people suggest to give the integrated dns server power over its own subdomain zone I did this by creating a NS record in my registrars dns management page but when running the command suggested in the redhat guide to check that it works it returns nothing this is the command i am running "dig @RegistrarsNameServerIPAddress +norecurse +short ipa.example.com. NS" but running a normal dig will show the record.

;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;ipa.example.com. IN A

;; AUTHORITY SECTION: ipa.example.com. 1799 IN NS ipa.example.com.

;; ADDITIONAL SECTION: ipa.example.com. 1799 IN A MyIPAddress

When trying to install using this subdomain I get this error right at the end. I have a feeling it is trying to add records to the integrated dns server but its not working properly. “Updating DNS system records ipa : ERROR DNS query for ipa.example.com. 1 failed: All nameservers failed to answer the query ipa.example.com. IN A: Server 127.0.0.1 UDP port 53 anwered SERVFAIL”

I think my main problem with this is I actually dont know how DNS delegates subdomain nameservers it always asks for a FQDN when putting in a nameserver but shouldnt this really be an ip address. If someone could give me and example NS record or how they have set it up that would be great I am extremely lost even some reading materials would be helpful all guides online just assume you already have setup the NS record and don’t give you too much information. Also I have replace all refrences to my domain to example.com (not actually trying to use example.com).
