As human beings, we’re accustomed to referring to web sites and file servers by name (i.e., www.google.com, www.microsoft.com, etc.). Of course, our computers must have an IP address to properly communicate to the rest of the world. What command line utility can be used to resolve an IP address from a host name?
A) IPCONFIG
B) TRACERT
C) NETSTAT
D) NSLOOKUP
The answer: D) NSLOOKUP
The name server lookup (NSLOOKUP) utility is used to query a domain name server to resolve an IP address from a name, or a name from an IP address.
The incorrect answers:
A) IPCONFIG
The IPCONFIG command provides TCP/IP configuration for network adapters.
B) TRACERT
TRACERT will trace the routing path through the network to a remote device.
C) NETSTAT
The NETSTAT utility shows a status of TCP/IP connections to a device.
