I think what the tool is complaining about is that the IP address of 
your server doesn't map back to the expected name:

In order to get rid of this warning, you'd need to talk to your ISP 
about the possibility of changing that reverse record, or of them 
delegating your reverse records to the control of your nameserver 
(possibly using the techniques of RFC 2317 if your range is smaller than 
a /24).

One of those is loopback; the other 2 are NAT'ted, so that information 
doesn't really help us...
