Strange appearance of a new Network Neighborhood
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
