Hello, all.
I have operated bind 8.x for authorative for some domain.
the domain is CNAME like this at that dns server
www.test.example.com IN CNAME www.xyz.test.example.com.
www.xyz.test.example.com. IN A 192.168.151.234
But I can see lots of messages like below(about 3~5% of the total query)
Oct 6 19:40:26 ns named[29298]: denied recursion for query from [121.xx.xx.x].33244 for www.test.example.com IN
and when I test using dig, above "denied recursion for query from " messages occur
only that doesn't answer using A record(only CNAME)
a)
www.test.example.com IN CNAME www.xyz.test.example.com.
www.xyz.test.example.com. IN A 192.168.151.234
b)
www.test.example.com IN CNAME www.xyz.test.example.com.
I would like to know when the dns answers a(95%) or b(5%)?
and the client get an answer b), what would be happen?
is there any problem or not?
Thanks for your help.
