127.0.0.1 - IP Loopback Address

By February 28, 2007

Follow me on:

| Definition | 127.0.0.1 is is a special purpose IP address conventionally used as a computer's loopback address. Messages sent to loopback IP addresses like 127.0.0.1 do not reach outside to the local area network (LAN) but instead are automatically re-routed by the computer's own network adapter back to the receiving end of the TCP/IP stack.

It is my understanding that the 127.0.0.x class is handled entirely in software. That is to say the the looping function is performed at the IP level, and never reach the network adapter. Which is true? Thanks
