Ping community servers using Command Prompt

Does anyone know the command to ping a community servers using Command Prompt?

This is what im trying to ping:

Server name: EU-GermanRust.eu [Wiped 19.12]
IP: 84.200.70.89:28010
( You can connect via Console press F1 and write net.connect 84.200.70.89:28010 )

Open cmd and type

Okay ty. The reason I do this is because I can connect to the server, but I get disconected after 3 sec ingame.

I got this to work ones by continues pinging the server using -T. But it dont work now.
