Depending on the needs of your domain, DNS records may need to be refreshed or updated periodically. DNS was designed with the ability to change the Time to Live (TTL) for each DNS record. The TTL setting dictates how long information in a record will be stored in a resolver or recursive name server’s cache.
TTL is an important part of DNS as it can greatly affect query volumes and it directly impacts propagation speed for users. The content a user will be served is based upon the information resolvers have in the cache.
This tutorial shows you how to change the TTL setting for a single record.
The ideal setting for TTL values depends on the type of record and how often the record is likely to change. For example, if you are using advanced DNS configurations such as Failover, the TTL values for these records should be set much lower than records that rarely change, such as an MX or TXT records. For recommended values for all DNS records, click here.
The TTL for your record has now been changed successfully. If you need to adjust the TTL for a batch of records, please visit our Bulk Change TTL tutorial.
