IPv4 Address Starts with 50.50...

[Take 0]

So I'm trying to port forward my ip so that my friend and I can play... minecraft... (i know) but every guide says that all ip addresses start with 192.x.x.x and I'm wondering if it starting with 50 50 would interfere with anything.

Also "Local Area Connection" doesn't show up in "Change adapter settings." And changing the properties of Ethernet just disconnects me from the internet.

192.whatever is always a local address, as in someone connected to the same router as you.
50.50 is.... not a local address.

There's too much to this to write it all out, it's not terribly complicated:

The IPv4 addresses reserved for private LAN use are:

10.x.x.x
172.16.x.x - 172.31.x.x
192.168.x.x

https://en.wikipedia.org/wiki/Private_network

Using 50.50.x.x for your LAN will work, unless you try to access a server on the Internet (like a website) with the same IP address. Then your router will send your packets to the local network instead of the Internet. The above private network IP addresses were reserved specifically to prevent this problem.

Port forwarding does not make your internal IP addresses visible to the Internet (and your friend). All it does is forward traffic sent to your router's public IP address to that specific port forwarded IP address on your private network. So this is not a reason to use 50.50.x.x.

Personally I use 10.x.x.x because it's easier to remember, and isn't used as much as 192.168.x.x so there's less chance of an IP address conflict when I use a VPN. Just be sure to set your subnet mask to match the range of IP addresses. A 0 in the subnet mask indicates the number can vary, a 255 indicates it's fixed. So a subnet mask of:

255.0.0.0 combined with 10.0.0.1 for your router's IP would allow all IPs up to 10.255.255.255.
255.255.0.0 combined with 10.11.0.1 would allow IPs up to 10.11.255.255.
255.255.255.0 combined with 10.11.12.1 would allow IPs up to 10.11.12.255.

(It's a bit more complex than this, but that should be good enough for 99.9% of people who just want to know what numbers to enter to get it working.)

I think I worded this incorrectly, my ip was already set to 50.50.x.x, I know I can change it if I need to, but I was wondering if there was a reason it was set to that

It's based on your geographical location, and it's what the ISP assigned you.

If your external (public) IP address is 50.50.x.x, that's just what your ISP has assigned you. Looks like the 50.32.0.0 to 50.55.255.255 range is owned by Frontier Communications. So your ISP is probably Frontier, and that's the IP address they've randomly assigned you.

If your internal (private LAN) IP address range is 50.50.x.x, then someone configured your router incorrectly. It should be one of the three IP ranges I listed above (10.x.x.x, 192.168.x.x, etc). Setting it to 50.50.x.x means you would be unable to communicate with Frontier customers who were randomly assigned an IP address in the 50.50.x.x range.

That's not as big a deal as setting it to the same IP address as a major web server, but it could still cause mysterious problems if you're doing something which requires peer to peer communications, like running a Minecraft server. Anyone with an IP address in the 50.50.x.x range trying to connect to your server would be able to send data to your server, but your server would be unable to send data back to them.
