How do I increase my TTL?
Posted by Darren Radsmith on 31 December 2009 02:44 PM

The TTL is the amount of time that your record will cache in remote systems / resolving name servers. So the longer the TTL the less frequent remote systems will lookup your DNS record and the less query traffic you receive. The shorter the configured TTL, the faster DNS changes propagate in servers that have cache data, however the higher the volume of query traffic you receive.

DNS Made Easy suggests all records that are using DNS Failover or on Dynamic IP's have TTL's set anywhere from 180 to 600 (3 to 10 minutes cache). Records that are static and don't change often should have TTL's set between 1800 (being on the low end) to 86400 seconds (30 minutes to 1 day cache). Any added NS records or glue records for vanity DNS configuration should have high TTL's set. DNS Made Easy allows you to set your TTL as low as 5 seconds. 

You can modify the TTL of an individual record or make a global change. To modify the TTL of a single record you would access the "DNS - Managed DNS" menu and select a domain name. Select the "Records" tab if it is not already selected. Simply double click a record to edit its TTL. To make a global TTL change, you can use our Bulk Update to modify TTLs.
