Hi,
I apologise if this is a noobish question regarding the Friend IP firewall settings but I noticed that Avast has a number of IP addresses listed automatically on my friendly list, what exactly are these IP addresses? Avast is clearly listing them as low risk/friend IPs but I’m not entirely sure what they are.
listing the IP here may help 
There are servers all over the world. The numbers are on servers.def file.
Sorry, I’ve been rather busy off the computer.
I figured out that one of the friend IPs is in fact my own home network. The other numbers that appear are 127.0.0.0 which appears to be down as something called “Loopback”? The other two listed are 10.0.0.0 which I can’t identify and 172.16.0.0 which also appears to be unidentifiable. There were listed on my friends list upon installation by avast, I was just unsure what they were and if they could cause any issues with my computer. Please forgive me but we are entering a realm of internet computer knowledge that goes over my head somewhat.
I actually have a question about the firewall within Avast IS 7 as well and figured I’d ask it in this thread since I imagine some of you could probably resolve my first question with ease.
When switching the firewall to it’s default settings how often does auto-decide actually block connections coming in/out? When I switch the firewall to it’s more aggressive setting it seems to block connections very frequently yet when on medium and auto-decide i’ve yet to see anything be blocked.
I noticed that with Public settings there are a few frequent connections between .1 or .2 on my IP addresses to .4. These are blocked by public settings and allowed by work/medium. Is this normal behaviour on a network? They are TCP and UPC protocol and on the same 443 local port.
I have the firewall set to public whilst I find these things out just to be sure but would appreciate any information you guys could share, thanks.
I actually had a few other things to ask as well about this,
Am I okay simply keeping my computer set to Public Firewall settings? I am pretty sure in the past month or so having avast/the trial last month, I’ve had my firewall set to Public (I’m one of those people who likes the whole strong security settings thing). I was just wondering if this would have an adverse affect on my recieving things like windows updates of 7?
I’ve noticed in the connections list where it tells you what has been connecting something showed up as a “loopback” as one of the connections. When I set the firewall to the work/medium setting it seems to not have any record of blocks on this particular connection. Is this normal behaviour from the internet?
With the settings set to public in the last few minutes there have been a number of connections attempting to come in, again these don’t seem to appear on the block list when the firewall is set to “Work”. Am I to assume that the things don’t appear on the block list because the Win firewall is dealing with them?
The connections include:
0.0.0.0 which appears to be the talk talk network according to the details finder.
46.4.26.78 which is something called “Hetzner Online” from Germany
173.194.41.168 which is from Google.
239.255.255.250 which seems to have no location (pin is central off the coast of africa) and is labelled is a “Multicast” (this literally attempted a connection a second a go).
Are these familiar to anyone else on here?
There are also a number of connection attempts from my IP for our network where various number devices have connected, why would it be showing connections between 2 and 255 or 2 and 5 when my IP for this machine is none of these… is it accounting general connections on the network too?
If anyone could help put my mind at ease I would be most appreciative, I am still currently leaving my firewall set to Public for the time being in the meantime, as I mentioned yesterday.
