Dynamic record - is a record with timestamp information.

Static record can only be updated or deleted from the DNS server on-command by the administrator or another program.

Static record - is a record that doesn’t have timestamp information (it will instead have the word “static” printed on its timestamp properties).

It can store the original zones records, or a secondary server which communicates directly with the primary and copies the records directly through a DNS mechanism. They have data that is saved in their system. The authoritative servers don’t cache query results. The requests that reach them are from Resolving name servers (resolvers) and the authoritative servers will either have the complete answer or they will pass to the name server who is responsible for it. They will not respond to recursive queries too. These DNS servers are giving responses to queries just for the zones they are configured. It has been configured from the original source, and it returns answers to queries that have been predetermined by the administrator. Such a server is the name server, which has the original zone records. It will try to find it in other recursive servers, but if it can’t, it needs to get the IP address from an authoritative DNS server. But if the data is outdated, this recursive server need to find the IP elsewhere.

The ISP has a recursive server, which might have the needed information cached in its memory. When you write a domain name in your browser, a DNS query is sent to your internet service provider (ISP). The authoritative DNS server is the final holder of the IP of the domain you are looking for.
