This allows multiple servers to run on the same system but still receive their requests, such as the case with many large hosting servers today. Requests are redirected depending on how they were made to the machine such as the URL that was used.</p> <p>Proxies can also provide other benefits such as distributing traffic among multiple instances of the same web server, formatting the requests such as adding additional headers, filtering requests, or adding an additional security layer.</p>/2022/02/creating-a-local-dns-with-coredns/Sat, 12 Feb 2022 00:00:00 +0000/2022/02/creating-a-local-dns-with-coredns/<h1 id="what-is-a-domain-name-system">What is a Domain Name System?</h1> <p>A Domain Name System (DNS) acts like the the phone book of the internet. When we enter a URL in our browser, it sends the URL to a DNS server to look up the actual IP address. Many times a DNS server will not know the IP address of the URL and it will have to forward it on to additional DNS servers. The next server to ask is determined by reading the URL from right to left. Each section of the URL is referred to as a zone and the remainder of the URL is forwarded on to the next zone.</p>
