I am building a network and right now, my internal IP is in the 100.100.100.x Range.

Should I change it to something like 192.168.1.x or 10.10.10.x or something? I don't want to conflict it with another Internet Site's IP Address.

The reason I chose 100.100.100.x is because its easy for me to type those numbers in. Should I change the IP Address to something else?

I would alway suggest to use addresses, reserved for private use.
If you absolutely need easy to type ip addresses, use something like 10.0.0.x or something like that.

Yes, use a Class C Private IP address like 192.168.x.x. That will give to up to 255 private IP addresses. More than enough for most home users. 10.x.x.x is a Class A IP address and will giver you millions of addresses, more than you will ever need.

Randomly picking numbers for IP addresses is never a good idea.

As long as you don't let them get to the internet, you have no issues at all.

Sure there are rules about ip addressing. And under certain scenerios it can be an issue when wanting to have a public presence.
But like any consenting adult, what you do on your side of the router is nobody's business but your own.
That's one of the cool byproducts of routing and firewalling.
