What is an unrestricted static ip address?
This is a fixed IP address.
Within a Local Area Network this can be used for servers or printers.

A single IP address also has ports numbers (~60,000) that can be used for various functions. e.g. Web Server, FTP server, Email server, Remote Desktop etc. Unrestricted access would allow all the computing functions that you need on the one IP address.

What are computer networks? I'm glad you asked. A given company or organization may have more than one computer, and can arrange for these computers to be connected (in more than just the way all computers can connect by way of the internet) so that they share programs, have access to each other's data, etc.

A PC system is an arrangement of PCs associated together with the end goal of sharing assets. The most widely recognized asset shared today is association with the Internet. Other shared assets can incorporate a printer.
Think of a computer as a block of flats and a port as each pigeon hole. You connect to the computer but then you have to decide what service you want from that computer. For example you can get web (HTTP) on port 80 or FTP on port 21. These port numbers can be changed by those are the defaults.
Basically when you have lots of different programs running on one server you need to have a way of saying which program you want to speak to.
