NAT

Short for Network Address Translation, which is an Internet standard that translates a private IP address within one network to a public IP address, either a static or dynamic.

This differs from client/server architectures, in which some computers are dedicated to serving the others. Peer-to-peer networks are generally simpler, but they usually do not offer the same performance under heavy loads.

Ping

A utility to determine whether a specific IP address is accessible. It works by sending a packet to the specified address and waiting for a reply. Ping is used primarily to troubleshoot Internet connections.
