I'm still doing something wrong.

Obviously it is telling me that I am doing something wrong . . . I have
read too much and I'm confused.
On dtdc01 I ran the following:
root at dtdc01:~# nslookup dtdc01
Server: 192.168.16.49
Address: 192.168.16.49#53
Name: dtdc01.dtshrm.dt
Address: 192.168.16.51
root at dtdc01:~# nslookup dtdc03
Server: 192.168.16.49
Address: 192.168.16.49#53
Name: dtdc03.dtshrm.dt
Address: 192.168.16.49
root at dtdc01:~# nslookup 192.168.16.51
Server: 192.168.16.49
Address: 192.168.16.49#53
51.16.168.192.in-addr.arpa name = dtdc01.dtshrm.dt.
root at dtdc01:~# nslookup 192.168.16.49
Server: 192.168.16.49
Address: 192.168.16.49#53
** server can't find 49.16.168.192.in-addr.arpa.: NXDOMAIN
In my mind I am being told to add the second DC (dtdc03) reverse dns to
dtdc01 . . . what am I doing wrong? Am I miss understanding the message?
