Now my ISP Uses GSNAT I hear, and it indicates gateway feeding me is 100.72.128.1.
Am I correct that the subnet above is necessairy so the 100.72.186.158 IP Can connect to the server at 100.72.128.1?

Thanks
 
The subnet mask 255.255.192.0 is a /18 so the router 100.72.128.1 would be the first IP address for devices. The last would be 100.72.191.254. Your assigned IP is somewhere in the upper part of the subnet's 16k IP range.

Did you mean CGNAT?

IPv4 addresses are almost exhausted so most ISPs are using NAT (Carrier Grade NAT, CGNAT, Google it). If you want to access services behind your router you must ask your ISP to remove you from the CGNAT and assign a real public IP.
