What is ICMP and IGMP?

The major distinction between ICMP(Internet Control Message Protocol) and IGMP(Internet Group Message Protocol) is that, IGMP is employed to form cluster of hosts, whereas ICMP is employed to send error messages and operational data indicating by hosts.

What is UDP and ICMP?

The primary difference is that TCP and UDP are for transferring application data (i.e. whatever the app desires), whereas ICMP is a “control” protocol that transfers information about other protocols.

Is ICMP the same as UDP?

Unlike the Internet Protocol (IP), ICMP is not associated with a transport layer protocol such as TCP or UDP. This makes ICMP a connectionless protocol: one device does not need to open a connection with another device before sending an ICMP message.

What does ICMP stand for?

Internet Control Message Protocol
The Internet Control Message Protocol (ICMP) is a protocol that devices within a network use to communicate problems with data transmission.

What does UDP stand for?

User datagram protocol
User datagram protocol (UDP) operates on top of the Internet Protocol (IP) to transmit datagrams over a network.

What is ICMP and when would you use it?

Internet Control Message Protocol (ICMP) is used to send control messages to network devices and hosts. Routers and other network devices monitor the operation of the network. When an error occurs, these devices can send a message using ICMP.

What port does ICMP work on?

Firewall rules for ICMP (TCP/UDP port 7)

What is ICMP and why it is used?

What is IGMP in networking?

The Internet Group Management Protocol (IGMP) manages the membership of hosts and routing devices in multicast groups. Multicast routing devices use IGMP to learn, for each of their attached physical networks, which groups have members.

What is UDP in networking?

User Datagram Protocol (UDP) – a communications protocol that facilitates the exchange of messages between computing devices in a network. It’s an alternative to the transmission control protocol (TCP). In a network that uses the Internet Protocol (IP), it is sometimes referred to as UDP/IP.
