Hello, all

The support for PTR records for IPv6 addresses was actually added a while back. By default, the each Droplet with IPv6 enabled will be configured with a single IPv6 address. This is the address that will be used for any PTR records that will be generated for domains pointing at your server. Like with IPv4, if the hostname given to the Droplet is a FQDN, the PTR record will be generated automatically.

If you’re looking for more control over PTR records more generally, there is an open request for allowing users to manually set PTR records. Please vote for it on UserVoice if that’s something you’d like to see:

Hope that this helps! Regards, Alex

To set the PTR for the IPv6 address:

All you need to do is temporarily change the name (Domain) of your droplet to something other than what it was set to when you enabled IPv6.

Then wait 1 minute, and change it back to the Domain Name you originally set it to before adding IPv6.

For example:

My domain was set to ser1.example.com. I enabled IPv6. I would change the domain to temp.example.com. Wait 1 minute. Then Change the domain back to ser1.example.com.

I hope that this finally resolves your issue.

As we do not support /64 subnets per customer at this time, we currently block all SMTP traffic over IPv6. As a result of that block, we do not implement PTR records on IPv6 at this time (as SMTP is the only significant use case requiring a PTR record).
