Changing TTL for DNS Record

Time To Live, or TTL for short, is somewhat like an expiration date that is put on a DNS record. The TTL serves to tell the recursive server or local resolver how long it should keep a record in its cache. The longer the TTL, the longer the resolver holds the information. The shorter the TTL, the shorter amount of time the resolver holds that information. Having a short TTL enables DNS records to propagate faster which is useful when making DNS changes.

TTL values are recorded in seconds. So for example a 3600 second TTL would equal one hour. The standard value typically used in cPanel is 14400 - four hours.

Shorter TTLs can cause heavier loads on an authoritative name server, but can be useful when changing the address of critical services like web servers or MX records, and therefore are often lowered prior to a service being moved, in order to reduce possible disruptions.

When working with the cPanel Zone Editor, the TTL can be changed. Below are the steps you can follow in order to modify the TTL value for your domain.

  1. Navigate to your cPanel’s Zone Editor -

  2. Click Manage next to the domain you want to edit:


  3. Click Edit for the records that you want to make changes to:


  4. Change the TTL field from 14400 to your new value, and click Save Record
