Here’s an analogy to make it a little more human-friendly:Īn IP address is the physical street address of a business complex. A port identifies a specific application/service running on that computer, like SMTP.Mail servers are much like website servers in that, while there might be a user-friendly front-facing domain name, the actual communication happens via IP addresses, like 222.501.285.45 (for more on how this happens, check out our introduction to the Domain Name System, or DNS).Ī “port” is another way to help computers ( like two mail servers) communicate with one another:
Then, the outgoing mail server needs a way to transfer your email to the recipient’s incoming mail server. The support is rapid and outstanding, and their servers are the fastest for WordPress.įor example, when you send an email, your email client needs a way to upload the email to the outgoing mail server.
