How to Resolve an IP Address Conflict

Please help me. I am living in a university dorm and therefore have no access to the router, just my ethernet cable. The problem goes away when I connect with wifi but I prefer to use ethernet as the connection runs faster roughly sixty people use the wifi on my floor alone.

What's an IP Conflict, and How Do You Resolve It?

I have never set up any sort of network with my ethernet and as far as I am aware all of my security is up to date, so is someone possibly using my network? When I reset my IP I have tried this method and manually resetting it the problem will go away for several hours to days but returns. Not really sure what to do, is there a very very simple way to ensure I am keeping my internet secure?

I got the same message this morning. I guess that was the reason for the pop up message.

Just know: Private IP, used by you and everyone who ever bought a router. Also, cellphones use local IP created by your Cell Co. Private IP cannot see the web, no device on the web would respond directly to a private IP.

The are localloop IP, I used to love it when I was in Cisco's Academy. Every device on a network has to have a unique IP address. That's the same if it's a home network, an office intranet or the internet.

What is an IP conflict?

However, we cheat. Think of your home network. Your laptop, computer, phone, tablet, games console The point is that they aren't on the same network. Your wifi router, or switch has a publicly facing IP address assigned to it by your ISP whenever it's turned on. That's the only "internet ip" you have - all of your devices are behind that IP, so appear online to have the same IP, whilst all having different IP's on your home network.

And it's not just home networks! If you've set up your first website, you probably went with shared web hosting. Most low cost shared webhosting plans also do not have their own public IP address. Even mobile phone companies do this. As for internal to every device, that's the MAC address.
