Question dig -x someIPaddress +trace no longer works


Hello!

I used to check reverse DNS by using the following command on my CentOS 5.7 machine via SSH.

root@server [~]# dig -x someIPaddress +trace

and it would give me a listing of results of the IP address from ARIN to wherever the PTR/NS records were stored. Now, it just returns the following:

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.4 <<>> -x someIPaddress +trace
;; global options: printcmd
;; Received 12 bytes from 4.2.2.1#53(4.2.2.1) in 11 ms

which is definitely different than how it used to work.

I've searched all over to see if maybe a kernel upgrade changed this, or something like that, but haven't found anything relating to it.

Does anyone have any idea why or how this happened? Also, if you are familiar with this command and the way it used to return results, is there some other command that does something similar?
