CDN allows the distribution of website content globally. When a visitor comes to your website, they will be sent to the server geographically closest to them. Thus leading to websites that load faster and offer lower latency. As the name aptly suggests, Content Delivery Network, or CDN, is a server network across multiple geographic locations. The purpose of such a network is the swift delivery of data to the end-users from servers closest to their site.
Like other providers, Psychz Networks also has an edge server, which is basically an edge device that provides an entry point into a network. These are edge servers because from the leading network through to each of those servers, the traffic passes over the companies' private network, but once it hits that server, it is exposed to the outside world.
Psychz Networks provides a list of IPs available for edge servers to which you subscribe to the CDN cluster. You can use IP ranges to filter incoming traffic on your origin website through firewall rules. Whitelisting edge server IPs enables a firewall to accept incoming traffic from IP addresses within the range and block malicious traffic.
Following is the list of Psychz Networks CDN Edge Servers IPs, which you should whitelist in your origin Server firewalls.
