Solved Significance of external IP address shown on my home network

Dell Inspiron black 15r notebook
August 25, 2015 at 06:20:32
Specs: windows 8.1
I received a notification on my laptop that a device from a certain IP address had connected to my home network. I looked up the address using herdProtect and it apparently relates to a domain share.earthlink.com with the explanation that it is an address commonly used on 'millions of devices'; then there is a list of downloads which is where I get confused. Is this list applicable to my downloads specifically, or general examples related to earthlink because one of them is: 5/68 Malware; related to a download manager. Should I be worried?

I'm thinking you mean "SOHO router" when you say "hub" If I'm correct, you should be able to connect to the management interface of the router and look for a list of connected devices. Also, if the device is not presently connected, you could check the logs to see what has connected. Those logs would also likely list any forwarded connections from external sites if there are indeed any.

If that should ever pop up again, compare against the IP address of your PC or against the DHCP scope of the router. If it's within the same subnet then it is indeed a LAN device and not someone connecting from an external source.

I'm not familiar enough with Windows 10 to know what you're talking about other than I know what a tile is. What application popped up within the tile to tell you about the connection is more what I was asking about.

earthlink.com is an ISP. Who is your ISP?

I find it odd your laptop is reporting an external IP connecting to your LAN. Is your laptop acting as a firewall sitting between the internet and your LAN?

What program/application on your laptop was reporting this connection?

What was the destination of this external connection? Did it connect to your laptop or another device?

Do you have some kind of port forward setup on your router that allowed this connection?

You say 'Home Network' so I assume you have a router with its firewall set up. Unless you are logged into the router's set up or if it has a feature to notify you of incursions via email or otherwise and you set this up, it probably was a fake notification. If it came in via email, delete it, if it just popped up on your monitor, run Malwarebytes, it probably is malware and clicking on it would probably give it permission to do all kinds of stuff (downloads, installs, etc) to your system(s).

You have to be a little bit crazy to keep you from going insane.

It was tile (?) that appeared on my screen (Windows 10) and I now cannot find where it is on the computer! Grrrr. It showed icons of the hub, and two devices. Could the IP address be a phone that was on the wifi too? The laptop is connected via ethernet but other devices (phone) are wifi but never resulted in that before. Ran malwarebytes but nothing detected. Any other scan I can run?

Thanks Curt R. I went onto the hub management and it seems that it is to do with a LAN device so all is good. I'm still getting used to Windows 10 myself so every little difference has me trying to figure out what it is!
