I have recently switched from a managed dedicated server to a unmanaged one. So now I have to run my own DNS. All seems to work fine except the DNS test gives an error for the MX that it does not have a reverse DNS entry. Well, I have set it up with BIND and checked and received it all was fine and a DIG on my server showed all right info. However any other server showed issues.
After some trial and error I found that I actually do not manage the PTR for the IP ranges assigned to me.
Well, my host is actually flexible and would allow me to have my /29 and /27 range delegated to me. Alternatively they can point the PTR records for me on their side.
Well, this brings me to my questions.
Are there pro and cons on having the range delegated to me vs having them point the PTR? They do not want to give me a recommendation and I really do not have enough DNS knowledge if there is any issue if I manage them myself using my BIND server.
I would appreciate some feedback from someone that is really knowledgeable on DNSA set-up since I am not sure what the best practive would be for me.
