I use Comodo FW on all my PCs. I’ve noticed that when left for a day or two it will detect a second LAN #2. Is this normal? I usually block access out of paranoia but it happens on ALL machines so I’m guessing is a quirk of nature.
Is this second network safe/neccesary/something? What is it?
You’ll need to provide a little more information regarding the IP addresses detected, for both LAN 1 and 2.
How do I do that? I usually add LAN #2 to blocked zones but cannot even figure out how this time. Regular as clockwork over three PCs on 3 different networks, LAN #2 always makes a showing after a couple of days.
Aha! Hiding in a new tabbed interface!
Well now…
LAN #1 is my own network/internet gateway starting 192. LAN #2 is 169.254.42.216. Not sure if it is the same across three PCs as they are at different residences. But always crop up after a couple of days of fresh install.
If you have a home network, chances are you’re using one or the reserved addresses ranges, probably something like 192.168.1.x/255.255.255.0. This will probably equate to LAN #1. The other address you’re seeing 169.254.42.216. is known as an APIPA (Automatic Private IP Address) and falls within the range 169.254.0.0/255.255.0.0 An APIPA address is issued to a PC, on a private network, when a DHCP server is unavailable, or cannot be contacted. There is no reason to block this.
OK, thanks. Was feeling paranoid! Will unblock & consider myself educated.
