Tools Used to Query Name Servers

Tools Used to Query Name Servers

Introduction
It is possible to manually query a DNS server in the same way that a
host on the network would query it, although this is often performed
by an application and the results are not explicitly displayed to the user.
The most common tools and utilities used for manually querying a
DNS server, are:
• NSLookup.
• DiG.
• Host.
• Sam Spade.
NSLookup
This command line utility can be found on UNIX and Windows based
operating systems. Its sole purpose is to query DNS servers, primarily
for troubleshooting, but can also be used to gain valuable information
about the target domain.
