Strange appearance of a new Network Neighborhood

Question

Hi all,
I just opened up my "Shared" section in the finder, about to go to the hard disk on my other computer and, lo, there's a network neighborhood there that I've never seen or heard of. (This is a desktop mac connected to the internet through a NAT router with firewall options on.)
The "Neighborhood" that is sitting there is
e3381.b.akamaiedge.net
I've searched the discussion forums and have seen reference to akamaiedge.net in relation to "Back to My Mac" (Which I'm not using). But even if I was using it, should I see this neighborhood in the finder at all?
Any clues as to how my computer found this network, and why it might be showing it to me? Should I worry about an intrusion?
Thanks
Kirk

Answer 1

I run a little shell script when I need to clear caches:
(I forget why sync is needed, somebody smarter than me suggested it, and said it should be done twice, but he also deleted swap files, perhaps it had something to do with that...)
file: cleancache.command
#! /bin/bash
sudo rm -Rf /Library/Caches;
sudo rm -Rf /System/Library/Caches;
sudo rm -Rf ~/Library/Caches;
sudo sync;
sudo sync;
sudo reboot
Doing this got rid of the artifacts in the Finder for me also.
But I want to know why they appeared in the first place. Do I have a flaw in my network setup that is allowing/causing this to happen? Is it a security concern?
