DHCP is a layer-4 protocol, most commonly transported over UDP. UDP port number 67 is the destination port of a server, and UDP port number 68 is used by the client
The client process needs a temporary port number. It tells the server to which port to reply (the TCP or UDP header includes information about the source and the destination port). The client, on the other hand, doesn't know in advance what port the server uses - unless the server uses a standard port number.The client process needs a temporary port number.

By default a TFTP server will accept connection requests on UDP port 69.
Conventionally, an HTTP server listens on port 80. Regardless of the brand of web server that you are running, the server will typically listen for HTTP traffic on port 80 and HTTPS traffic on port 443.
Port 69 and UDP are used for tftp transmissions.
No. It use TCP. Port No. is 25. It's use for Email routing between mail server.
DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. When the length of the answer exceeds 512 bytes and both client and server support EDNS, larger UDP packets are used.
Port No. for Tranmission Control Protocal (TCP) is 6 Port No. for User Datagram Protocol (UDP) is 17
UDP port 123. (UDP is a connectionless protocol that sacrifices reliability for speed and bandwidth).
In computer science, a port is a number - commonly used in the TCP and UDP protocols - used to distinguish different applications on a computer. Ports are also used to distinguish different data flows on one computer. For example, if I connect to a Web server, the destination port will be port #80 - that way, the destination computer knows that the data should go to the Web server, and not to some other application. And the origin port might be, for example, port #1024 for one file I get from the server, and port #1025 for another file I get from the same server.In computer science, a port is a number - commonly used in the TCP and UDP protocols - used to distinguish different applications on a computer.

There are a lot of differences between a DNS port and UDP. An example would be DNS is for translation while UDP actually relays the host communication.
