I know. Why is the external IP of my server and my laptop the same? Is is because of my router using DHCP?

Router assigns you local addresses to share network. The external ip address is your real ip-address of your node(modem). So it will always remain the same because the connection is single. May change if you reboot your modem. That is, it is DHCP assigned by your ISP switch/router. It is your own router that assigns you different ip addresses.

external ip will always be the same (It is provided by the isp). You may have to buy ip's if you want more than one.
I dont know what will happen in case of ipv6.
Thats why there is NAT to have different ip's in your internal network. You can do port forwarding in your router. Why do you want different external ip's ..?

I don't want different IPs. I was just unsure how that worked. It does make more sense for the modem to have the IP since then only one IP is used for all the devices on my network. There a limited number of IPs after all. We must conserve them.

I have noip.com setup, so how do I ssh to my server using the the created NAME.no-ip.biz?

You need to setup openssh server first and then from client
$ ssh username@noip domain
