ICMP - Internet Message Control Protocol (Internet Control Message Protocol)

ICMP is responsible for error handling in the network.

ARP - Address Resolution Protocol

ARP - Used to find the hardware address of a computer's network card based on the IP address through IP.

RARP - Reverse Address Resolution Protocol

RARP is used to find the IP address of a computer's network card based on the IP address of the hardware address.

BOOTP - Boot Protocol

BOOTP is used to boot a computer from the network.

PPTP - Point to Point Tunneling Protocol

PPTP is used for connections (tunnels) between private networks.
