Netstat
A TCP/IP troubleshooting utility that displays statistics and the state of current TCP/IP connections.
nbtstat
A TCP/IP troubleshooting utility that provides information about NetBIOS names and their addresses.If you know the NetBIOS name of a workstation, you can use this to determine its IP address.
tracert
A TCP/IP troubleshooting utility that uses ICMP to trace the path from one networked node to another, identifying all intermediate hops between the two nodes.
Nslookup
A TCP/IP utility that allows you to look up the DNS host name of a network node by specifying its IP address or vice versa.
NAT
A technique in which IP addresses used on a private network are assigned a public IP address by a gateway when accessing a public network.
slash notation
In CIDR, a method of denoting network IDs and their subnet boundaries.Example might be 199.34.89.0/22.
