strategies to mitigate DNS amplification attacks in ISP network

2015-12-01 Thread Martin T
Hi, as around 40% of ASNs allow at least partial IPv4 address spoofing in their network(http://spoofer.csail.mit.edu/summary.php) and there are around 30 million open-resolvers(http://openresolverproject.org/) in the Internet, then DNS amplification traffic is daily occasion for ISPs. This in prob

The answer is: It depends. :) In the case of Akamai, for a standard streaming or HTTP service, the IP address is not dedicated to a single customer. Also, Akamai is not going to give you a list of IP addresses serving your content. This is specific to Akamai, and for a general Akamai customer.
