Does the static IP provider specify it, or is it an arbitrary number you pick from a range?

For instance, where the proxy format would be: https://username:password@static_IP_address:portNumber

The answer is closer to "a number you pick from a range".

TCP works by having, among other fields a source and destination IP address and source and destination port. These 4 things are required for a unique session.

The port is a 2 byte number, so between 0 and 65535. Services are commonly associated with default ports, but these are typically just by convention. There is 1 bit which, depending on your OS may not be - on some OS's ports below 1024 are only accessible by the superuser account.

It is, of-course, the server that defines the port here.

  • Could you advise me on (or confirm) the following? I'm hoping to narrow down what information I should request from a client paying for this static IP. Along with the static IP address, I assume I should ask for the username/password, http type (http or https), and the port number. I want to be confident that I ask for nothing unneeded.

  • Your question in the comment does not follow. What service are you providing this client?

  • To clarify, he's not paying me for the static IP. He's my client in a related capacity, the point being I want to be sure not to confuse him. He needs to send me a paid proxy IP address I will use in an application I built for him (if that helps to know).

    I don't understand why you need anything more then the static IP address of his VPN. I still don't understand where a proxy comes into it. As to port ranges the VPN provider does not assign port ranges, it assigns an IP address. Ports are a property associated with an IP address [ for a TCP connection] and are determined by his computer and your server.

    [1] - in the sense that nothing has been rebutted on your end yet (you didn’t specify where I was wrong in my original and subsequent explanations).
