Lesson Summary

■

IP is responsible for ensuring that a datagram sent across a network reaches its destina-

tion. TCP and UDP are transport protocols. ICMP implements TCP/IP messaging and is

used by the ping command. DHCP automatically configures computers on a network

with their TCP/IP settings. DNS resolves a hostname or FQDN to an IP address. ARP

resolves an IP address to a MAC address.

An IP address identifies a computer (or other network device) on a subnet. A subnet

mask defines the range of IP addresses on a subnet.
