I have played with DNS a lot lately, and i have found that some big companies's web sites uses the Akamai NS as the Name Server for thier 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: 126.96.36.199 > 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: 188.8.131.52
I have looked up at the Akamai website, but couldn't find the exact problem it suppose to solve for its users, but i could understant that it is relate to security (maybe to prevent DDOS attacks).
Is anybody knows what kinds of attacks it suppose to solve ? or maybe i am just wrong and there isn't any relation to security but to outsourcing the DNS management?
