I have played with DNS a lot lately, and I have found that some big companies' web sites use the Akamai NS as the Name Server for their WWW servers, for example:
$>nslookup > www.redhat.com Server: 192.168.43.1 Address: 192.168.43.1#53 Non-authoritative answer: www.redhat.com canonical name = www.redhat.com.edgekey.net. www.redhat.com.edgekey.net canonical name = www.redhat.com.edgekey.net.globalredir.akadns.net. www.redhat.com.edgekey.net.globalredir.akadns.net canonical name = e86.b.**akamaiedge**.net. Name: e86.b.**akamaiedge**.net Address: 220.127.116.11 > www.ynet.co.il Server: 192.168.43.1 Address: 192.168.43.1#53 Non-authoritative answer: www.ynet.co.il canonical name = ynet.co.il.d4p.net. ynet.co.il.d4p.net canonical name = a39.g.**akamai**.net. Name: a39.g.**akamai**.net Address: 18.104.22.168
I have looked up at the Akamai website, but couldn't find the exact problem this is supposed to solve for its users, but I could understand that it is related to security (maybe to prevent DDOS attacks).
Does anybody know what kinds of attacks it is supposed to solve? or maybe I am just wrong and there isn't any relation to security but to outsourcing the DNS management?
