Find your IP address - support.microsoft.com Mar 21, 2019 ipv4 - Ping a private IP address in another network A PC in a private IP range can't be acccesed from the public internet.. Devices in private range connecting to internet use a proxy or router/NAT device that replaces the local source IP for a single public IP address that redides in your router/NAT.. However, you can make an exception to that, opening a port in the router and allowing that traffic directed to your public IP adddress and that monitoring - Ping Equivalent For Checking If A Port Is Is it a specific port you need to check e.g. port 80 for http or port 21 for ftp, or is it a specific IP address you need to check i.e. to test if the host is reachable. The latter is what your above example is doing. – Chris Feb 8 '11 at 13:16
The TCP tool will “ping” an IP address at a specific TCP port and report if the host accepts the connection. The syntax is IPAddress:PortNumber (e.g. 220.127.116.11:80) Great use for this tool is to test if your servers are open on specific ports.
