Domain Name System Tcp Port. They need to reserve a port for each connection request to serve as the connections endpoint. Domain Name System DNS in Application Layer.
In this command represents the fully qualified domain name FQDN of the KMS host computer and represents the TCP port that KMS uses. Also the DNS server binds to port 53 but the query itself originates on a random high-numbered port 49152 or above sent to port 53. The local domain tree is the system TCPIP domain name DMNNAME and each parent domain with two or more parts to the domain.
Here is an example on how to display the DNS port parameters.
Instead you can use a WINS server or an Lmhosts file for name resolution. By default DNS servers use port 53 to send and receive queries for domain names. An example UDP socket address for a DNS server would be similar to 2030113153. And both client and server support EDNS larger UDP packets are used.
