Setting Time To Live (TTL) for a DNS zone using WHM

Introduction

• The Domain Name Service (DNS) service converts human-readable domain names (for example: example.com) to computer-readable IP addresses (for example: 192.0.32.10). DNS is based on the "DNS zones" that exist on the server. to convert the domain name to IP addresses.
• WHM offers the ability to set Time To Live (TTL) for a DNS zone through the functionalities DNS Functions. TTL specifies how long a DNS server caches a DNS record before requesting an update from the authoritative name server, measured in seconds.

Requirement

• WHM credentials. This data can be found in the management email of the reseller account or VPS with cPanel/WHM.

Steps

• After logging in to the WHM panel on the left side of the page we will go to the section DNS Functions and we will click on Set Zone Time To Live (TTL). Alternatively, we can look for this menu using the search field in the upper left.

• On the next page we will select the domain for which we want to make the changes. In the field New TTL:  we will set the value TTL desired in seconds. If we use a DNS cluster (multiple nameservers synchronized with each other), we can check the option Do not sync changes across the DNS cluster, if we do not want the changes to synchronize on all nameservers.
  After completion we will click on Set TTLs.

• If everything went smoothly we will be greeted by a confirmation message of the form:
