Question:
Do I really need to have 3 IP addresses for my CDN edge server?
Environment:
OnApp CDN
Answer:
The 3 IP address requirement is a security measure for your CDN edge server. The three IP addresses are used to give each user on the server a unique combination of ips, so that that if there is a DDOS attack, it can be located. The edge server needs multiple IP addresses in order to produce this combination.
