Cyber Security and Domain Name Systems Deploy and Protect Network With DNS Sinkhole Blackhole

DNS is a protocol within the standards for how computers exchange data on the Internet, known as TCP/IP protocol suite. A DNS server, also called a name server, handles a massive database, which maps domain names to IP addresses. The Domain Name System (DNS) [1] is central to the operation of modern networks, translating human-readable domain names into machine-usable Internet Protocol (IP) addresses. DNS makes navigating to a website, sending an email, or making a secure shell connection more accessible and is a crucial component of the Internet's resilience. As with many Internet protocols, DNS is one of them which not withstand abuse from wrong actions intent on causing harm. “Protective DNS” [2] is different from earlier security-related changes to DNS. It is a security service – not a protocol – that analyses DNS queries and takes action to mitigate threats, leveraging the existing DNS protocol and architecture.
