👉 DNS engineering is the strategic optimization of Domain Name System (DNS) infrastructure to enhance performance, reliability, and security for domain name resolution. It involves advanced techniques such as implementing DNS load balancing, using Anycast routing to distribute traffic efficiently, and optimizing DNS query response times through caching and compression. DNS engineers also design and deploy DNS security measures like DNSSEC (Domain Name System Security Extensions) to prevent attacks such as cache poisoning and ensure data integrity. Additionally, they optimize DNS resolution for global reach by strategically placing DNS servers in edge locations and utilizing content delivery networks (CDNs) to reduce latency. Overall, DNS engineering aims to create a robust, scalable, and secure DNS infrastructure that supports high availability and efficient domain name resolution.
