(Bug) Server permits adding RRs that should not be acceptable #751

Closed noseshimself closed 8 months ago

noseshimself commented 9 months ago

Simply put: It is possible to add RRs that result in having CNAME and other RRs for the same name without any error messages.

While I do not really care about the results of lookups for these names but other servers are complaining about the zone; secondaries running BIND are not accepting the zone data (but only complaining about the fact "CNAME and other data" without giving the name -- lovely) and other servers just drop the result reporting NXDOMAIN for ANY queries.

Please add a CNAME sanity check.

Thanks for the feedback. Will get the validation added.

Technitium DNS Server v11.5.2 is now available that adds CNAME validation check. Do update and let me know your feedback.
