looped ports

By m.sajjad.m ·
Hi all,
I use a software (Active Ports by to view the TCP/IP ports activity in my systems. I am looking that ---> connection and ---> connection in my all NT server computers. The over all functionality of servers is OK, but I am still worried about this looped ports action. Is it a bug, or internal function?

by tech_wiz03 In reply to looped ports is the pc's loopback port and it is regularly active in some configurations to do handshaking. It can be used to pass network information sent from the console back to running programs either as a test of legit network responce or as a means of passing information internally between processes that don't have a preset method of talking to each other.

I use this software on my win2k pro & server also. But no such activity on these machines. What about that?

Beleave me! is the loopback. It never leaves the pc that it is on, never talks to network external to the pc. That IP address is specifically reserved for the purpose I just mentioned. NT servers must have a loopback port defined but microsoft removed that constraint on win2K and winXP. You can still set-up a loopback port on these other operating systems but now must do it manually.

If you still need convincing look it up under ip dotted quad standards and prerequistes, ip addressing fundamentals, network protocols and theory.

best regards
