What this tests is the standard port used for HTTP communication. The default port for HTTP traffic is 80, meaning when you access a site with http:// and don’t specify a port, your client connects to port 80 on the server. This convention lets web servers listen for unencrypted web requests in a predictable way. For contrast, HTTPS uses port 443, and 8080 is a common alternative for testing or running a secondary web service, not the default HTTP port. Port 25 is used for email (SMTP) and isn’t related to web traffic. So 80 is the commonly used port for HTTP.
