The Domain Name System (DNS) protocol is an important part of the web's infrastructure, serving as the Internet's phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.
Hello all I seem to be having trouble forwarding DNS to my server. I have setup port forwarding 53 TCP/UDP to my server IP, but when I test it I only get a responce from TCP. To test I set port 53 to UDP only and it failed outright. Just wondering if I'm missing something. Regards Fred Apr 17, 2018 · The stand-alone server running Windows Server 2003 becomes a DNS server for your network. In the first step, you assign this server a static Internet Protocol (IP) address. DNS servers must not use dynamically assigned IP addresses because a dynamic change of address could cause clients to lose contact with the DNS server. Server Port Test.

For example, if a computer needs to communicate with the web server example.net, your computer needs the IP address of the web server example.net. It is the job of the DNS to convert the host name to the IP address of the web server.
What Is DNS Server Or Protocol Port Number? – POFTUT
Everyone knows that DNS servers use UDP port 53 for queries, right? Well something that I recently learned was that DNS servers also use TCP port 53 to do zone transfers (axfrs). Make sure to open that port up in your firewall if you are allowing zone transfers from your DNS server. Knowing that sooner could have saved me a lot of time! What Is DNS Server Or Protocol Port Number? TCP or UDP. DNS can use both transmission protocols TCP and UDP. But general usage is over UDP protocol because of its TCP Port 53. One of the used DNS port is TCP Port 53. TCP provides stability over DNS resolutions process.
