Using TTL makes websites faster since they can be received more quickly if the DNS lookup has already been cached locally rather than needing to go through the complete lookup procedure on a DNS server.

Caching DNS records is undoubtedly very helpful for increasing speeds and lowering the strain that DNS resolvers worldwide endure. Setting your Time to live too high, however, can lead to problems. For instance, if a DNS record needs to be changed, the change won’t go into effect until the TTL has passed. The propagation period is what we refer to as this.
