dns nslookup failure

[Kevin Darcy]

Yes, you could have the colo set up the reverse records, but then you'd 
have to go to them every time you wanted a change. If you have a /24 
range or bigger, then the colo could delegate the relevant reverse 
zone(s) to your nameservers, so you could maintain the reverse entries 
yourself. If you have a range smaller than a /24, then you'd have to go 
through something like the RFC 2317 mechanism (basically, the other 
party needs to set up a CNAME record for each of your PTRs) to get 
control of your reverse entries. In any case, you should probably start 
by talking to your colo about what they are willing to provide and how.

                                                                         
                                             - Kevin
