How do I determine what my IP address is?

Some CCDC software and services require you to give us details of your IP address (or a range of IP addresses). This is your public or external IP address i.e., the IP address that the outside world will see when you access a website or web service from your computer. As such, this is useful information for CCDC when you need to access services such as WebCSD. Your external IP address will often be affected by use of a firewall or proxy server.

The easiest way to determine your external IP address is to visit a website that tells you your IP address. If you run a Google search for 'what is my IP address', Google will usually tell you directly in the search results, and you should otherwise see plenty of websites listed that do this.

Providing an IP range for a large number of devices

Providing a range of external or local IP addresses can allow access for a large number of users to CCDC software and services without specifying an activation key. The details given above can provide individual IP addresses and could be used to determine a small range, but for large scale ranges we would recommend you first discuss with your systems administrators what range(s) would cover your access requirements to ensure CCDC provide the correct access for you.
