What Are the Common Uses for 127.0.0.1?

A common technique to verify that a computer’s networking equipment, operating system, and TCP/IP implementation are working correctly is to send a ping request to 127.0.0.1. Based on the results of the test, administrators or computer users can troubleshoot network connectivity issues. Application developers also make use of the loopback address to test basic network functionality when developing a program or application component prior to going “live” on a network or the Internet with testing or deployment.Some of the “lighter” uses of the loopback address are to trick computer security or computer science students into attempting to crack, probe, or test network speed by using the 127.0.0.1 address. There are also a number of variations on the “World’s Worst Hacker” found across the Internet. In these stories (which at least a few are likely based on true stories), fellow hackers urge “newbies” or a “less-than-knowledgeable” hacker to infect, hack, or conduct a DOS or DDOS attack against the 127.0.0.1 address. In the more humorous stories, the hacker succeeds in infecting or deleting information from his or her own computer to the amusement of those watching.
