The IP address in the PDF 172.20.1.234 is an example IP address! Please look up the IP range of your network with the command "ipconfig" in a CMD Window (on Windows PC). Mostly the IP address is something like 192.168.X.X. That is the IP range from which your C-MOR IP address has to be picked.
Lets say your Windows PC has the IP 192.168.1.100. Then you C-MOR must has something like 192.168.1.X, eg. 192.168.1.90.
Please consult somebody who is a little bit familiar with IP addresses. This will be resolved quickly.
