Question

PTR record with no managed DNS?

  • Posted September 4, 2014

I have DNS managed offsite with an A record pointing to my DO droplet. I’ve named my droplet the FQDN I’d like (sub.domain.com). Should this setup result in my PTR record resolving correctly?

I must be doing something wrong because diging results in status: NXDOMAIN.

PTR records escape me a bit but, so I’m clear: as the owner of the IP, DO is ultimately responsible for setting this record, right? I’m not barking up the wrong tree, am I?

EDIT: Colleague stopped by and pointed out the TTL according to the SOA record is a full day. I created the instance about a day ago and renamed it within a day—possible that it just hasn’t propagated yet?

Yes the PTR record is set by DO. It is the name of your droplet. . Once the change is made it will take several hours to propagate out.

Hello there.

DigitalOcean automatically configures the reverse DNS entry (PTR) on their end. It will be the hostname you choose when you set up your droplet. You can change/check this in the control panel by selecting your droplet, then settings, then rename. As it says, changing the name there will update the PTR but not the hostname of the system, that is something you will need to do, instructions for that vary depending on the system you have installed.

Hope that this helps!
