FAQ 98: What is considered a concurrent client?
Category: Initial setup | Updated: 11/16/2011 3:23:15 PM
Concurrent client/user/device is interchangeable and defined as:
The total number of devices that have an IP address which at any given time are resolving DNS through the DNS Redirector server.
This is NOT a cumulative total...
For example; if you had 40 clients on one day, and 90 clients on the next, and 55 clients on the following day - you do not need a 185 client license. Since the peak number of clients was 90, that's the minimum license you need, and the closest license pack we offer is 100 simultaneous clients.
Your license should cover the peak number of simultaneous clients, plus a little room for growth.
One way to determine how many clients you have is too look at the DHCP server and see how many IPs are being handed out, realize this doesn't account for devices with a statically assigned IP address.
When you've reached 15% over the licensed number of clients, additional clients will cause DNS service to stop, this is reflected in the daily log file.
You can increase your license at any time by paying the difference. You should "true-up" annually when you find the number of concurrent clients has grown past your license.
