adig - print information collected from Domain Name System (DNS) servers adig [OPTION]... NAME...

Add any additional description here

Send queries to DNS servers about NAME and print received information, where NAME is a valid DNS name (e.g. www.example.com, 1.2.3.10.in-addr.arpa).

This utility comes with the c-ares asynchronous resolver library.

-c class Set the query class. Possible values for class are ANY, CHAOS, HS and IN (default).

-d Print some extra debugging output.

-f flag Add a behavior control flag. Possible values for flag are igntc - ignore query truncation, return answer as-is instead of retrying via tcp. noaliases - don't honor the HOSTALIASES environment variable, norecurse - don't query upstream servers recursively, primary - use the first server, stayopen - don't close the communication sockets, and usevc - always use TCP.

-h, -? Display this help and exit.

-s server Connect to specified DNS server, instead of the system's default one(s). Servers are tried in round-robin, if the previous one failed.

-t type Query records of specified type. Possible values for type are A (default), AAAA, ANY, AXFR, CNAME, HINFO, MX, NAPTR, NS, PTR, SOA, SRV, TXT, URI, CAA, SVCB, and HTTPS.

-T port Connect to the specified TCP port of DNS server.

-U port Connect to the specified UDP port of DNS server.
