What is TTL?
TTL or Time to Live is the mechanism used to limit the lifespan of information circulating on the network. This prevents data from moving indefinitely across the Internet, improving privacy and performance.
When DNS zones or DNS records are modified, the time it takes for the update to take effect depends on the TTL value. This value indicates how long the information is cached on DNS servers, so until this time passes, propagation will not be completed.
cdmon DNS servers set the TTL for zone records to 900 seconds (15 minutes).
