What does netstat utility do?
Nbstat is a utility that displays protocol statistics and current TCP/IP connections using NBT (NetBIOS over TCP/IP), which helps troubleshoot NetBIOS name resolution issues.
What are netstat active connections?
“netstat -a” shows all the currently active connections and the output display the protocol, source, and destination addresses along with the port numbers and the state of the connection. “netstat -b” shows the executable involved in creating each connection or listening port.
What is the difference between netstat and nbtstat?
NetBIOS over TCP/IP status (nbtstat) is a command-line tool used primarily for diagnosing or troubleshooting NetBIOS name issues. Network Status (netstat) displays information on the IP configuration of a host, but goes further to show its connections, including ports, protocols, and metrics on the communications.
What is the difference between nmap and netstat?
Nmap is a Network mapping tool. That means it’s used to discover informations about hosts on a network (their ip, open ports, etc). Whereas Netstat is a network statistic tool used to list active connections from and to your computer. See https://en.wikipedia.org/wiki/Netstat.
How do I check if a port is open windows?
Open the Start menu, type “Command Prompt ” and select Run as administrator. Now, type “netstat -ab” and hit Enter. Wait for the results to load, port names will be listed next to the local IP address. Just look for the port number you need, and if it says LISTENING in the State column, it means your port is open.
What are netsh commands?

What does the command display in the nbtstat output?
Displays NetBIOS over TCP/IP (NetBT) protocol statistics, NetBIOS name tables for both the local computer and remote computers, and the NetBIOS name cache. This command also allows a refresh of the NetBIOS name cache and the names registered with Windows Internet Name Service (WINS).
How does netstat command work?
The netstat command symbolically displays the contents of various network-related data structures for active connections. The Interval parameter, which is specified in seconds, continuously displays information regarding packet traffic on the configured network interfaces. The Interval parameter takes no flags.
