Netstat will display statistics for ICMP such as Packets Sent and Received
Try netstat -s
ICMP messages arent data packets that are usable by a computers user but by the OS itself, they indicated issues with connectivity in response to requests that are being sent from the computer. For example your computer requests a web page from a particular IP address, if your router is unable to establish a connection to that it will send an ICMP message back to your computer to let it know why.
Common messages that get sent are:
Echo reply (Ping)
Echo request (Ping)
Destination Unreachable
Netstat monitors TCP\UDP ports on the computer to monitor connections to the machine, ICMP is a lower level prototcol (IP) and hence doesnt maintain connections or actively listen for ICMP packets
Netstat is a command-line tool that displays network connections and a number of network interface and network protocol statistics. It is used to find problems on networks and determine how traffic effects performance.
Used to see which active TCP connections are open and running on a networked host. Lists the protocols in use, the local address and port number, the destination address and port number and the state of the connection.
Explore few of the commands like Netstat &Nbtstat for Network Connections, Netsh for Firewall, Diskpart for Storage in Windows Server 2008.
It depends on the operating system you are using. For Windows based systems, at the command prompt, use the command 'ipconfig'. You can also use the 'netstat' command to get this information. For a Unix/Linux system, the command is 'ifconfig', although you may also use 'netstat' to find your IP address. also using internet Allaboutsite offers whatismyiptool to find your ipaddress. As the name suggests, this tool lets you instantly find out your IP address online. Just head to the page and see your IP address displayed at the top along with it's physical location on a Google map.

Active TCP connections
To display active TCP or UDP connections, you can use the command netstat -an in the command prompt or terminal. This command shows all active connections and listening ports, along with their respective IP addresses and port numbers. For a more detailed view, you can use ss -tuln on Linux systems, which provides similar information with additional options for filtering.
The command netstat provides information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. It can show all active network connections, listening ports, and the state of the connections. Additionally, it displays information about routing tables, interface statistics such as packets transmitted and received, and network protocol information.
Netstat reports on the common tcp/ip protocols, including (but not limited to) TCP, UDP, ICMP, socket connections.

netstat----------most useful and very versatile for finding connection to and from the host. you can find out all the mulitcast groups (network) subscribed by this host by issuing "netstat -g"netstat -nap | grep port will display process id of application which is using that portnetstat -a will display all connections including tcp and udpnetstat --tcp will display only tcp connectionnetstat --udp will display only udp connectionnetstat -g will display all multicast network subscribed by this host.
use the netstat command.
Netstat -e
The Windows netstat command; netstat -b (show the executable involved in creating each connection) netstat /? (list of available parameters)
netstat /all will show you all active connections
It will display the content of all routing tables, or a routing table for a particular address family.
The command netstat -an displays a list of all network connections and listening ports on a computer, along with their current status. The -a option shows all connections and listening ports, while the -n option presents the addresses and port numbers in numerical format rather than resolving them to hostnames. This command is useful for diagnosing network issues or monitoring network activity.
