What is a TTL?
TTL (time to live) is the amount of time that your record is cached in nameservers all around the Internet. If your IP changes often (or if you plan to move your computer to another IP) it is recommended to set your TTL to a lower value. Once your IP is on a static IP (or after you have transferred your system to the new IP) it is recommended to switch your IP to a higher value. The higher the TTL the faster the performance since most machines will have the value cached for a longer period of time. However a TTL that it too high often causes lengthy periods of downtime if your system is ever needs to switch IPs. All TTLs in DNS Made Easy are set is seconds. If your computer’s IP is static then a recommended TTL is 12 hours. (43200 seconds). If your computer is on a dynamic IP then it is recommended that your TTL is between 5 and 120 seconds.
