I have setup conditional DNS forwarding for certain subdomains but it is behaving in a way that I think is unexpected.
This is what I have setup.
sub1.domain.com -> 220.127.116.11 sub2.domain.com -> 18.104.22.168
Now if anything is going to abc.sub1.domain.com it does forward that dns request to 22.214.171.124. However, if there is a domain 123.abc.sub1.domain.com then it does not forward to 126.96.36.199 instead nslookup says that it did not get a response.
However, if I setup another conditional domain rule that says: abc.sub1.domain.com -> 188.8.131.52
then 123.abc.sub1.domain.com does resolve.
Is this by design? I thought it would act like a wildcard but it doesn't.
