I just found a new IP Address in my trusted zone and it's called a Loopback
Adapter with an IP address of 127.0.0.1. I have no idea what this is and
what it does - nor where it came from. Can someone help? In the meantime,
I blocked it.

Thanks...I looked up the article - but, unfortunately, didn't understand it
at all. How did it get there? What does it do? I'd sure appreciate it if
you could explain this to me in plain English. I just tried to load
Limewire - and it told me I had to change the settings on my firewall
loopback. So, I blocked the loopback adapter - and Limewire loaded. Is it
OK to block the adapter - or delete it? Thanks.....

Suggest leaving it blocked for a while, and see if you have any problems.
If no problems pop up then go ahead and disable it. I am running Win XP Home
SP2 and can not find anything on this machine about Loopback Adapter.

From what I understand it applies only if you are on a network system, and
are having problems. But I could be wrong.

I have XP home also and that loopback showed up after a boot a while ago. I
tried blocking it and it didn't affect anything and finally deleted it.

ZoneAlarm puts it there by default when you install the software. I have
6 computers that use ZA and everyone of them has that item listed. I'd
leave it there and keep it unblocked. There must be reason for it,
although I can't tell you what it is.

If you want more information I'd contact ZoneAlarm.

127.0.0.1 is the home address. It's the IP for the computer itself.
