The way the Anycast network works is by assigning a single IP which goes to all our datacenters.

Therefore, if you are coming in from broadband in Dallas, the Anycast IP will automatically determine the closest available server PoP (Point of Presence) to you.

To debug this – or have your clients debug this at any time, they can goto:

http://debug.netdna-cdn.com

The result of the page will be something like:

You are hitting the NetDNA Los Angeles Datacenter
Your ip address is: 66.159.202.156

This is a very handy tool in debugging.

Cheers.
