Do most large orgs give each person individual IPS
In a large organization say a hospital or a large regional office. Does each user get an actual IP address or do they tend to use NAT? and each user has a 192.168.x.x IP, and comes out on a single or a few WAN IPS?
We are trying to develop some code for an app we offer that will restrict multiple users from logging in from a single location if they have only paid for one license. One of the ideas is to restrict by IP.

If someone has a 192.168.* (for example) address then they are being NATed.
Restricting by IP doesn't work except in very specific, targeted cases. Offices and colleges are probably the two biggest LAN users.

I understand the 192.168.x.x. being NATed' My question is not how it happens but what is common. NAT or each user getting IP's in a large organization.

Big enough systems need sysadmins, and that means a LAN, and with IPv4 that means NAT.

Use of NAT is very common. IPv4 addresses are expensive, and the vast majority of businesses have no reason to give each computer in their network its own public IP.

Thanks that's what I thought.
The cost alone would be a factor.
