Is it possible to have multiple public IP addresses that are from different subnets going through one router? I have been told that this is not possible with most routers and that I would have to spend a lot of money on a router to be able to do it. I am still not totally clear on what defines a subnet even after reading up on them.

What I am trying to achieve:

-My office has 10 computers.
-All would be connected to one router.
-My internet service provider has provided me with 10 public IP addresses, that are all very varied (which I asked for)
Examples of the variation could be,
-I want each computer to have a unique public IP addresses assigned and fixed.

What I had been told was that most routers have been designed to receive public ip addresses that are in a range.
For example:

would be fine, but what I am after is not. Can anyone help? Thanks.

Do the computers need to share files with each other?

Think of subnets as logical divisions of a local area network that segregates groups of machines. One example might be having the computers from different departments each on their own subnet: accounting, marketing, legal, etc.

It is not critical that the machines share files with each other. They don't share at present, but possibly in the future I may want them to. I'd sacrifice my machines being able to share if I can get a setup where each computers public ip address is unique.

A very simple and inexpensive solution if you don't need to share files: you should be able to just connect all the computer Ethernet ports and the Internet cable to a 16 port switch, then configure each computer to use its individual Internet access address as its gateway. You really don't even need a router unless it is also your Internet modem, if so then you could just turn off DHCP and pass the Internet connection through to the router.
