I need to make reverse dns work for our network using Plesk and we have a /20 assigned to us. But that option is not presented when trying to do this for our space. So I assume that I have to do a /24 for each of those? Also, if I have a customer that hosts their own server and we need to reference that, say a /29, I don't see a way to do that either. If that address space falls within a /24 that would normally be our domain name, how do I do that?

Typically reverse dns is managed by the owner of the ip space, not who its leased to - so you may need to get your provider involved to get that done for you.

Sorry, should have explained. We are the ISP and own the IP space.

 

[Amin Taheri]

for us we contact our ISP (internap etc) and they do it for us. Have you tried contacting YOUR isp?

 

[tlkhorses]

Not clear I guess

I am the ISP.

I think everybody is suggesting you contact the organisation that assigned you your /20, as they will normally be responsible for the rDNS for the IPs.

If you have directly obtained your /20 from RIPE/ARIN/whatever then it is a different story -- but in that case I don't see why you'd be wanting to use Plesk for manage rdns? Seem like the wrong tool for the job to me.

Alternatively, if you have not obtained your /20 from RIPE/ARIN/whatever but the organisation you obtained it from has delegated rdns control to you, then....well, again, is Plesk really the best option here? A pair of dedicated dns boxes would seem more appropriate?

Sorry if none of this is appropriate to you or if I've misunderstood your question.

Guess I should have said it that way. Our /20 is assigned to us by ARIN (recently). Our DNS servers are currently hosted off site as well as a couple of other servers. Plesk is the tool they provide. So that is why I am in this situation. May move all that back local sometime in the future. Anyway, that is the reason I am asking.

Thanks,

Ah. I see. All makes sense then...apart from using Plesk for this task

My only suggestion would be to find a way not to use Plesk for this, but I know that isn't helpful to you

Hopefully someone with more knowledge in this area will come along and add something useful.
