Display current TCP/IP network connections and protocol statistics.
Syntax
NETSTAT [-a] [-b] [-e] [-f] [-n] [-o] [-p protocol] [-s] [-t] [-x] [interval]
NETSTAT [-a] [-f] [-p protocol] [interval] -y
NETSTAT [-r] [interval]
Options
interval Redisplay statistics, pausing interval seconds between each display.
(default=once only) Press CTRL+C to stop.
-a Display All connections and listening ports.
-b Displays the executable filename involved in creating each connection or
listening port*.
-e Display Ethernet statistics. (may be combined with -s).
-f Display Fully Qualified Domain Names (FQDN) for foreign addresses.
-n Display addresses and port numbers in Numerical form.
-o Display the Owning process ID associated with each connection.
-p protocol
Show only connections for the protocol specified;
can be any of: TCP, TCPv6, UDP or UDPv6.
If used with the -s option then the following protocols
can also be specified: IP, IPv6, ICMP,or ICMPv6.
-q Display all connections, listening ports, and bound nonlistening TCP ports.
Bound nonlistening ports may or may not be associated with an active connection.
-r Display the routing table.
-s Display per-protocol statistics. By default, statistics are
shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;
The -p option can be used to display just a subset of these.
-t Display the current connection offload state.
-v Verbose - use in conjunction with -b, to display the sequence of
components involved for all executables.
-x Display NetworkDirect connections, listeners, and shared endpoints.
-y Display the TCP connection template for all connections.
Cannot be combined with the options -b -e -n -o -r -s or -t.
* Where available this will display the sequence of components involved in creating the connection or listening port. (Typically well-known executables which host multiple independent components.) This option will display the executable name in [ ] at the bottom, with the component it called on top, repeated until TCP/IP is reached. The -b option can be time-consuming and will fail unless you have sufficient permission [elevation].
Display all connections and listening ports and repeat the scan after a delay of 30 seconds, repeating until CTRL-C is pressed:
NETSTAT -a 30
Display the executable filename and process Owning process ID:
NETSTAT -b -o
This output can be compared with TASKLIST -FI "PID eq 1234" where 1234 is the PID.
“Once you're on the network, you can do a command called NetStat - Network Status - and it lists all the connections to that machine. There were hackers from Denmark, Italy, Germany, Turkey, Thailand ...” ~ Gary McKinnon
BROWSTAT - Get domain, browser and PDC info.
ROUTE - Manipulate network routing tables.
PATHPING - IP trace utility.
PING - Test a network connection.
TASKLIST - Display running applications and services.
