Explanation:

Port 53 is used by the DNS service.

DNS (Domain Name System) is a distributed and hierarchical database, which stores the necessary information for domain names. Its main uses are the assignment of domain names to IP addresses and the location of the corresponding email servers for each domain. The DNS was born from the need to provide people with access to the servers available through the Internet, allowing them to do it by a name, something easier to remember than an IP address.

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.
