What would happen if the Router DHCP IP was out of the "private" range?

According to this site http://compnetworking.about.com/od/workingwithipaddresses/f/privateipaddr.htm you can set up your own custom DHCP IP on your router. The last two ranges are the only ones that seemingly can be changed e.g 192.168.0.0 through 192.168.255.255 . What if you made a custom IP that was 163.123.34.1 or some other random numbers? Would people be able to "hack" you because it is out the private IP range?

It just wouldn't work. The ISP's router wouldn't pass on the packets and, even if it did, any return packets would go to the legitimate owner of that IP address, not you.

And you shouldn't even try it. Why would you want to? There are plenty of private IP addresses available so just stick with them.

Hackers gain access via your public IP address, not your private IP. Your public IP is controlled by your ISP and can't be directly changed by you.

The private IP is irrelevant, unless the hacker is inside your network. In that case, you would have much bigger problems.
