Translation
Network Address Translation allow multiple
hosts to access the internet on a single public IP
address. Without NAT, only one host may be
assigned a public IP. NAT also helps protect
the local network from external threats.
Ping tests connectivity from a host to a remote
host using ICMP packets. It is a very common

A router routes packets between networks
based on an IP address. A route is the path
between those two networks. Routing is a
layer-three only, while local networks are
layer-two only.
