DNS root server under DDoS Attack

The DNS root server administrator reported two waves of attacks on January 1, November 30 and January 1, December 1. The attack time was from UTC to UTC on the first day, and from UTC to UTC on the first day. The IP addresses used for attacks are randomly distributed, but the domain name to be queried is not. The attack traffic is about 5 million queries per second. The Administrator said that the end user was not affected by the attack. The statistics provided by Verisign, which manages two servers, show that the average daily UDP query does not exceed 10 billion, and the number of daily queries exceeds 50 billion during the attack period. Administrators believe that source address verification and BCP-38 can be used to reduce the ability to abuse the network to launch attacks.
