The local DNS server caches the NS record. To exploit this architecture, SigRed involves configuring a domain's ("deadbeef.fun") NS resource records to point to a malicious name server ("ns1.41414141.club"), and querying the target DNS server for the domain in order to have the latter parse responses from the name server for all subsequent queries related to the domain or its subdomains.

DNS services are the services that run the Domain name System. The DNS services are considered to provide multiple servers in a specific geographical location where users may be spread in a vast area (Incognito Software, 2007).

The DNS recursor is a server designed to receive queries from client machines through applications such as web browsers. Typically the recursor is then responsible for making additional requests in order to satisfy the client’s DNS query. Quad9 routes your DNS queries through a secure network of servers around the globe. The system uses threat intelligence from more than a dozen of the industry’s leading cyber security companies to give a real-time perspective on what websites are safe and what sites are known to include malware or other threats. Using numbers from a site called DNSPerf, I found that a really fast DNS Server like Cloudflare had an average lookup speed of 12ms. Meanwhile, slow DNS Servers were turning in times of over 120ms per lookup. These delays may not sound like much, but delays of more than 100ms are noticeable. If a page needs to do several DNS lookups using a
