How do I ping a port in Windows Server?
How do I ping a port in Windows Server?
The easiest way to ping a specific port is to use the telnet command followed by the IP address and the port that you want to ping. You can also specify a domain name instead of an IP address followed by the specific port to be pinged. The “telnet” command is valid for Windows and Unix operating systems.
Can you ping with a port number?
Because ping doesn’t operate over a protocol with port numbers, you cannot ping a particular port on a machine. However, you can use other tools to open a connection to a particular IP and port and obtain the same information you would get if you could ping an IP and port.
How check ping port is open?
Enter “telnet + IP address or hostname + port number” (e.g., telnet www.example.com 1723 or telnet 10.17. xxx. xxx 5000) to run the telnet command in Command Prompt and test the TCP port status. If the port is open, only a cursor will show.
What port does Windows ping use?
Ping Uses ICMP Type 8 and Type 0 So there is no specific port number for the ping command. But the ICMP types Type 8 (Echo Message) and Type 0 (Echo Reply Message) are used for ping operation. The sender or pinger creates an ICMP packet with type 8 which requests the remote system to return an ICMP reply.

Does ping use UDP or TCP?
Ping uses ICMP(Internet Control Message Protocol). it does not use TCP or UDP. To be more precise ICMP type 8(echo request message) and type 0(echo reply message) are used. ICMP has no ports!
Does ICMP use port 0?
The most common example of this traffic is ICMP (Internet control message protocol), and a lot of network monitoring applications will still show “port 0” for ICMP. Port 0 will also show up if there’s fragmented IP traffic, like a DNS response which exceeds the historic maximum size of 512 bytes.
