When companies started outsourcing the hosting of their websites to the likes of Akamai and AWS, network teams learned quickly that many work- and non-work related applications shared the same IP address. Getting all the DNS logs is often impractical. Is Google hijacking DNS with DoH? What is NPM?

Dashboards for DNS Metrics Reveal Issues With Your Infrastructure. Working behind the scenes, Domain Name Server (DNS) is often overlooked, but it’s one of the most critical pieces of the Internet infrastructure. That point was driven home by the Mirai DDoS attack last October against the DNS infrastructure of Dyn, Inc.

For example, during an attack, service provider network engineers need to be skilled at finding attacks, choosing an appropriate mitigation strategy, and have proper access to the infrastructure to apply it. For destination-based RTBH, the victim’s destination IP address becomes completely unreachable.

Since the traffic behavior towards individual IPs is lost in the averages of the IP address pool, the result is a constant stream of false negatives.
