It is possible that the first discovered network was for the Automatic Private IP Addressing scheme with an IP address range of 169.254.0.1 - 169.254.255.254 you can see all defined networks that are defined in comodo by going to the network zones section under firewall settings and expanding each network zone name and noting the IP addresses.
Interesting I have never experienced this before but you can remove Home #2 and Home #4 as those are the Automatic Private IP Addressing I mentioned before. Also do you happen to have more than 1 network adapter that you use to connect to a network? Do you have VMWare installed or use any kind of VPN client or server software? How many adapters do you have listed under network connections?
Automatic Private IP Addressing (APIPA) is a network client-side process used as a fallback position when DHCP services are not available on the network but the client devices are configured to use DHCP for their IP address configuration.
The APIPA service also checks regularly for the presence of a DHCP server (every five minutes, according to Microsoft). If it detects a DHCP server on the network, APIPA stops, and the DHCP server replaces the APIPA networking addresses with dynamically assigned addresses
APIPA allows the client device to randomly choose one of the 65,534 addresses available in the Class B network address of 169.254.0.0/16. After choosing an address from this range, the computer sends an ARP request to see whether another device on the network is using that address, and if it is not, the client device uses the address.
Even though the device uses this made-up address, it continues to send out DHCP Discover broadcasts to locate a DHCP server on the network as soon as the DHCP server becomes available.
While waiting for a valid DHCP-delivered address, the device that is using an APIPA address can communicate with any other device on the network that is using an APIPA address.
If two or more devices are connected to a switch and the devices are using APIPA, therefore, all of them can communicate at least with each other, but not with any other devices on the network that are using proper addresses for that network segment.
Woke up to see that I had received another Comodo “Join a New Network” prompt for 169.254.x.x. during the night. Whew.
Also had a Comodo screen prompt to allow access by SYSTEM to “C:\Windows\System32\LogFiles\HTTPERR\httperr1.log”. I had this same prompt yesterday and allowed it. Today, it went away before I could re-approve it. Does the contents of this log file indicate anything as to why these new network prompts are occurring?
When I look at this log file, I see the following (all new since the Win10 upgrade).
169.254.x.x is a temporary IP for DHCP server research phase.
If your box does not respond to the request for allocation of IP your PC will stay 169.254.x.x
This is indicative of a config problem network
