TTL CALC

TTL stands for "Time to Live" when referring to a DNS record. When a networked device needs to convert a common name (like google.com, www.foxtrotmedia.com, etc) to numbers (like 3.12.8.49, or 69.69.4.20) it looks to the DNS "resolver" to provide those numbers. For faster access the DNS Resolver (like Verizon, Comcast or Domain Controller) will store these records locally to reduce latency. How long the DNS resolver should hold this record is determined by the TTL defined in the DNS record as a number in seconds.
