My firewall does not support using URLs.  What IP addresses should I use for www.syndetics.com?

Syndetics leverages a caching service called Limelight when you use www.syndetics.com. One of the major advantages to this service is much faster response times serving images – content that has been retrieved is cached close to the end user and the Limelight network is highly optimized for performance. The major disadvantage is we cannot guarantee what the IP address of www.syndetics.com is going to be on a particular day or for a particular customer. That’s determined by the Limelight network based on internet traffic patterns – and optimized multiple times an hour – so the IP address has the potential to change fairly frequently.

If you can't work with changing IP addresses, the alternative is to use http://syndetics.com or alternatively https://secure.syndetics.com. These names point directly at the product platform and bypass the Limelight network. The advantage to this method of connecting is you don't have to worry about the destination IP address changing. The disadvantage is all of the content will be served via our data center in Virginia, and it will bypass the geographically close caching which Limelight provides.

The IP addresses of those URLs are as follows:

syndetics.com - 165.215.210.43
secure.syndetics.com - 165.215.210.63
