TCP 53
The protocol that uses port numbers 67 and 68 is the Dynamic Host Configuration Protocol (DHCP). Port 67 is used by the DHCP server to receive client requests, while port 68 is used by the DHCP client to receive responses from the server. This protocol is essential for dynamically assigning IP addresses and other network configuration parameters to devices on a network.
The port that automates the assignment of IP addresses on a network is typically associated with the Dynamic Host Configuration Protocol (DHCP). DHCP servers use UDP (User Datagram Protocol) on port 67 for incoming requests from clients and port 68 for client responses. This protocol allows devices on a network to automatically receive IP addresses and other configuration settings, simplifying network management.
The IMAP (Internet Message Access Protocol) email protocol usually uses port 143.
What protocol is used by web servers and on which port ?
HTTP is the hyper text transfer protocol . The port used by HTTP is port 80 . The HTTP is the protocol of application layer.
port as a phone extension, with the computer's IP address being like its phone number. You can call the number (IP address) to talk to the computer, then dial the extension (port) to talk to a specific application. An application needs to be listening on a port in order to communicate. A Protocole is just the language that the two applications on either end of a conversation agree to speak in. If your application is sending streams of bytes to my application, my application needs to know how to interpret those bytes.
SMTP is a protocol using port 465. POrt 25 and 587 are provided for client sides. This protocol plays the basic role in transferring mails.
Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.Catalyst switches have support for several technologies that may be used in larger networks, and that are not available on home switches - for example, VLANs, and STP (Spanning-Tree Protocol), as well as options for port security.
SSH uses such port.
