What is dig and nslookup?

Dig (on Mac OS X and Linux) and nslookup (on Microsoft Windows) are the primary command-line tools for troubleshooting DNS issues. While web-based tools are convenient and easy to use, it is often faster to use a command-line tool on your own system.

Dnsenum is a multithreaded perl script to enumerate DNS information of a domain and to discover non-contiguous ip blocks. The main purpose of Dnsenum is to gather as much information as possible about a domain. The program currently performs the following operations: Get the host’s addresses (A record).

Where does nslookup pull?

nslookup is an abbreviation of name server lookup and allows you to query your DNS service. The tool is typically used to obtain a domain name via your command line interface (CLI), receive IP address mapping details, and lookup DNS records. This information is retrieved from the DNS cache of your chosen DNS server.

Which yum package has nslookup?

bind-utils package
You see that nslookup is part of the bind-utils package.

Why nslookup command not found?

What’s the difference between dig and host in Linux?

The host command is a little more descriptive. basically prints the same output. The dig command includes some timing stats and the actual query that will be performed. Although the output is in a different format, the information that is printed out is basically the same as dig.

What kind of algorithm does a DNS server use?

DNS servers use a round-robin algorithm during a query that involves recursion. So if your domain name lists two name servers as authoritative (one master, one slave) a remote DNS server (like mine) will alternate queries between the two name servers to fetch answers.
