Dig (command)
dig is a network administration command-line tool for querying the Domain Name System (DNS).
dig is useful for network troubleshooting and for educational purposes. It can operate based on command line option and flag arguments, or in batch mode by reading requests from an operating system file. When a specific name server is not specified in the command invocation, it uses the operating system's default resolver, usually configured in the file resolv.conf. Without any arguments it queries the DNS root zone.
dig supports Internationalized domain name (IDN) queries.
dig is a component of the domain name server software suite BIND. dig supersedes in functionality older tools, such as nslookup and the program host; however, the older tools are still used in complementary fashion.
In this example, dig is used to query for any type of record information in the domain example.com:
The number 172719 in the above example is the time to live value, which indicates the time of validity of the data.
The any DNS query is a special meta query which is now deprecated. Since around 2019, most public DNS servers have stopped answering most DNS ANY queries usefully RFC8482 - Saying goodbye to ANY.
If ANY queries do not enumerate multiple records, the only option is to request each record type (e.g. A, CNAME, or MX) individually.
