How do I add a PTR record?
First, you'll want to make sure you've set up your domain zone already and that it is resolving to your IP.
- Select your Linode
- Go to the "Remote Access" tab
- Click "Reverse DNS"
- Enter your Linode’s fully qualified domain name in the Hostname field
From here, you'll just need to confirm that a match has been found for your address.
You can find additional details in the Reverse DNS Guide
With the new interface it seems to be on the networking tab - click the "…" to far the right of the ip address.
but how long does it take to propogate to the linode DNS servers?
Yes @jasen you are correct, the Cloud Manager interface will be a different set of steps than what thorner has described, but the Reverse DNS Guide he linked to has the necessary instructions.
@chaetura, it should not take more than an hour for your rDNS changes to become visible.
Also consider checking the Linode guide to PTR records here for more info.
