What is TTL?
Time To Live (TTL) sounds like a horror movie, but luckily it is not related to people. It is the value that shows how long the information should be kept in a particular device. There are many pieces of data that have their own TTL value. Here we will see DNS TTL and CDN TTL.
When we are talking about DNS TTL, it is related to the time that the DNS resolvers must keep the DNS records in their cache. Each of the DNS records will have its TTL value. There are some with longer TTL because there is less chance that the value will change and others with shorter TTL value, where there are often changes.
