(WHM >> Home >> DNS Functions >> Set Zone Time to Live (TTL))
This interface allows you to set the value for time to live (TTL) in your server's DNS zones. The TTL specifies how long a DNS server caches a record before it requests an update from the authoritative nameserver, measured in seconds.
Set Zone TTL
To set the value for TTL, perform the following steps:
- Select the zone(s) that you wish to update from the menu.
- Enter the TTL in the text box. This value must be a positive integer. The default TTL is 3,600 seconds.
- If you have multiple DNS servers and do not want the TTL to synchronize across your cluster, select the Do not sync changes across the DNS cluster checkbox.
- Click Set TTLs.
The system will update the TTL values for the selected zone(s).
