What is PTR (Reverse DNS)?


A PTR record (also called reverse DNS or rDNS) maps an IP address back to a hostname. Correct PTR records are commonly required for email reputation and service validation.


Update PTR in Classic mPanel


Open your server in Classic mPanel:

  1. Log in to your BinaryLane account.
  2. Navigate to your server within the mPanel.
  3. In the server page, locate the Reverse DNS line in the 'Network' section
  4. Click the blue hypertext link next to Reverse DNS (you can also access the 'Reverse DNS Name' settings page for your server by clicking the settings icon (⚙️) followed by selecting 'Change Reverse DNS').



Set the PTR value:

  1. Enter the hostname you want for reverse DNS.
  2. Click Button: 'save'.

Navigate to your server within the new mPanel:

  1. Log in to your BinaryLane account.
  2. Navigate to your server within the mPanel.
  3. Find the Reverse DNS row.
  4. Click the same blue hypertext link next to Reverse DNS (you can also access the 'Reverse DNS Name' settings page for your server by clicking 'Network' from the left-hand pane).



Set the PTR value:

  1. Click the 'Edit' button next to the current rDNS.


  2. Enter the hostname you want for reverse DNS, then click the 'Tick' button to save.


Apply and propagation time


Important
PTR/rDNS updates can take up to 12 hours to fully propagate.


After saving, allow time for DNS propagation before testing email delivery or reverse lookups.

Verify the change:

You can verify the reverse DNS record using common lookup tools once propagation has completed.
