Example 1: View all active network connections and ports
netstat
Description:
This command displays a list of all active network connections and their associated ports.
Example 2: View network statistics and information
netstat -s
Description:
Comprehensive network statistics and information are displayed here, including receive and send statistics, errors and dropped packets.
Example 3: View detailed information about network connections
netstat -an
Description:
This command displays detailed information about active network connections, including IP addresses and ports in use.
Example 4: Displaying listening ports
netstat -an | find "LISTENING"
Description:
Only the ports that are waiting for incoming connections are displayed here.
Example 5: View DNS statistics for network connections
netstat -anb
Description:
This command displays DNS information alongside network connections, including associated executable files.

Displays protocol statistics and current TCP/IP network connections.
NETSTAT [-a] [-b] [-e] [-n] [-o] [-p proto] [-r] [-s] [-v] [interval]
-a Displays all connections and listening ports.
-b Displays the executable involved in creating each connection or
listening port. In some cases well-known executables host
multiple independent components, and in these cases the
sequence of components involved in creating the connection
or listening port is displayed. In this case the executable
name is in [] at the bottom, on top is the component it called,
and so forth until TCP/IP was reached. Note that this option
can be time-consuming and will fail unless you have sufficient
permissions.
-e Displays Ethernet statistics. This may be combined with the -s
option.
-n Displays addresses and port numbers in numerical form.
-o Displays the owning process ID associated with each connection.
-p proto Shows connections for the protocol specified by proto; proto
may be any of: TCP, UDP, TCPv6, or UDPv6. If used with the -s
option to display per-protocol statistics, proto may be any of:
IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.
-r Displays the routing table.
-s Displays per-protocol statistics. By default, statistics are
shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;
the -p option may be used to specify a subset of the default.
-v When used in conjunction with -b, will display sequence of
components involved in creating the connection or listening
port for all executables.
interval Redisplays selected statistics, pausing interval seconds
between each display. Press CTRL+C to stop redisplaying
statistics. If omitted, netstat will print the current
configuration information once.
Important information, tips for the "netstat" command
Yes, there are some important points to note when using the `netstat` command:
1. Options and Parameters:
- Exact options may vary depending on operating system. Use `netstat /?` or `man netstat` (for Linux) on the command line to see the available options.
2. Admin rights:
- To view all information you may need administrator rights. Therefore, run the commands as an administrator, especially if you need detailed information about all connections.
3. Active Connections:
- The standard `netstat` command shows active connections. Make sure you know which connections should normally be present on your system to detect suspicious activity.
4. Filter and Sort:
- Use additional options like `-a`, `-b`, `-n`, `-o`, etc. to filter or sort the display. For example, `netstat -an` displays the IP addresses and port numbers instead of using host and service names.
5. Firewall and Security:
- Note that `netstat` gives you information about which network connections are active on your system. Monitor output regularly to detect suspicious activity. However, keep in mind that `netstat` alone is not enough to protect your system from security threats.
6. Understanding connection states:
- The output of `netstat` contains various states such as "ESTABLISHED", "LISTENING", "TIME_WAIT", etc. Understand what these states mean to correctly interpret the network status.
7. IPv4 and IPv6:
- Depending on the system configuration, `netstat` can show both IPv4 and IPv6 connections. Be careful about which address families you want to monitor.
8. Periodic Review:
- Run `netstat` periodically to detect changes or unusual activity. This can help identify potential security issues early.
Please note that this information is general in nature and may vary depending on the system and environment. If in doubt, it is advisable to consult specific documentation or resources for your operating system.
