In this article we will discuss The nslookup Command, will make brief discussion on The nslookup Command, In last article we discuss about DNS Message Format.
When configuring a network device, one or more DNS Server addresses are provided that the DNS client can use for name resolution. Usually the Internet service provider (ISP) provides the addresses to use for the DNS servers. When a user’s application requests to connect to a remote device by name, the requesting DNS client queries the name server to resolve the name to a numeric address.
Computer operating systems also have a utility called nslookup that allows the user to manually query the name servers to resolve a given host name. This utility can also be used to troubleshoot name resolution issues and to verify the current status of the name servers.
when the nslookup command is issued, the default DNS server configured for your host is displayed. The name of a host or domain can be entered at the nslookup prompt. The nslookup utility has many options available for extensive testing and verification of the DNS process.
use the Syntax Checker activity to practice entering the nslookup command in both Windows and Linux.
