What is the dns port number and dhcp port number?
DHCP listens for incoming on UDP 67 and send out on UDP 68 For 'well known' and 'registered' ports, you can check http://www.iana.org/assignments/port-numbers too. by gerson.freire@terra.com.br
What is the default port number DNS?
DNS uses port 53. DNS queries are generally performed via UDP, and zone transfers are normally done via TCP.
When a client computer sends a request to a Domain Name System (DNS) server, what type of packet is sent?
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.
What is the most significant difference between the Layer 4 TCP and the Layer 4 UDP?
the main difference between UDP and TCP is that UDP is not a reliable protocol.
Example of application used by the UDP and TCP?

What is the tftp port number?

Why does DNS run over udp?
DNS runs over UDP because the UDP does not have any delay to establish the connection, which DNS will have finer application level control for faster connection speed in comparison to TCP protocol.
What are the specific port no of tcp and udp?
Port No. for Tranmission Control Protocal (TCP) is 6 Port No. for User Datagram Protocol (UDP) is 17
What is ntp port number?
UDP port 123. (UDP is a connectionless protocol that sacrifices reliability for speed and bandwidth).
