TTL – Definition and Best PracticesTTL – Definition and Best Practices

What is the definition behind TTL?

TTL, also referred to as time to live, is a setting that is frequently used to specify how long a DNS record should stay in a DNS resolver’s cache. 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.

Today we will explore one of the most fundamental DNS record types, which exactly is the SOA record. First, we will see what is its definition and then we will take a look at its structure. Finally, we will explain why is SOA record so critical for properly working the Domain Name System.

The PTR record, or also known as a pointer record, has a very precise and important function. Its goal is to link the IP address to the domain name. In addition, there is a piece of good news, and it is able to perform successfully both with IPv4 addresses and IPv6 addresses. Moreover, this type of DNS record is an essential piece required for you to have Reverse DNS. It is able to exist only in the Reverse DNS zone. So, it would be best if you did not place it in the Forward DNS zone.
