All my device IPs are the same?

[turkeymaster77]

So I'm using a linksys router (Linksys EA6300) to connect all my devices both wired and wirelessly. Each device is getting its' own internal ip address just fine (with the 192.168.1.* format), but when I query google on ALL devices it returns 107.4.34.114 as the external ip.

It gets even weirder when I plug a pc directly into my Comcast modem. At this point ipconfig returns my ipv4 as 10.0.0.10 and google says that my ip address is 2601:404:c300:4c5b:f0f0:33b:6011:38bc??

What is going on here? I'm simply trying to locate the ip address that will work for some simple port forwarding, however when I use the 107.4.34.114 it keeps timing out.

ANY help or thoughts are appreciated guys. Thanks for reading!

Welcome.

Every device must have an IP. Your external IP is your Internet IP. Nearly all of us at home have only one. So your router routes traffic from one external Internet IP to several the proper internal private IP. That is your 10.0.0.0 range.

Yes, that long scary looking IP is IPv6. That is a whole other matter. With IPv6 every device can have their own external IP. It all depends on how you setup your router. For compatibility, local link IPv6 IPs also exist so you got two scary IP numbers to deal with.

For simple port forwarding, focus on the private IP. However, it's been nearly a decade since I had to manually setup such things. What did you want to do?

Thanks for responding. It's silly really, I'm just trying to set up a minecraft server so that users on other networks can have access.

I have the router set to forward port 25565 on my current device (192.168.1.101), and I can connect to the server right now when using that ip. However when I use my external ip www.canyouseeme.org just times out and so does minecraft.

Thanks again!

That's good news that you made it that far. I assume when you connected successfully that you did it from the same computer that is the server, if so try a different computer to that 192.168.1.101 address. That checks that the port is open on that server.

Next thing to try is to test that port externally. You can try Steve Gibson's Shield's Up. Make note of what it says is your external IP now get past the 1st few screens to a portion where you can 'User Specified Custom Port Probe' and enter 25565. I understand that canuseeme does a similar test, but Steve's also will tell you if it's open/closed/stealth/non responsive.

It is Not "silly" to be "ignorant". () - - .

If it is passing the ShieldUp test (as mentioned above) to connect from the outside to your Network/Server the user has to put in the browser (or the App).

107.4.34.114:25565 (using your numbers as given above).

This is telling the outside computer go to the Network that is on Internet IP 107.4.34.114 and there connect to the Network Device/Computer that its port is 25565 opened.

What ever port is opened has to be unique to one computer and the computer's Firewall has to allowed it in too.

If your modem is also a router you may have to forward the port there as well or set the modem to bridge mode. The ip address "10.0.0.10" is curious, but I've seen netgear routers change their address to something similar in order to avoid conflicts with another router on the same network.

I find it easiest to disable the routing functions of one router on the network and allow the other one to perform that duty for simplicity's sake (this is essentially what bridge mode does). My own network consists of a cable modem in bridge mode with a trendnet router behind it performing all the routing on the network. That way the modem is doing nothing but providing an internet connection and I only have to forward ports on my trendnet router.
