.SH NAME |
|
adig \- print information collected from Domain Name System (DNS) servers |
|
.SH SYNOPSIS |
|
.B adig |
|
[\fIOPTION\fR]... \fINAME\fR... |
|
.SH DESCRIPTION |
|
.PP |
|
.\" Add any additional description here |
|
.PP |
|
Send queries to DNS servers about \fINAME\fR and print received |
|
information, where \fINAME\fR is a valid DNS name (e.g. www.example.com, |
|
1.2.3.10.in-addr.arpa). |
|
.PP |
|
This utility comes with the \fBc\-ares\fR asynchronous resolver library. |
|
.SH OPTIONS |
|
.TP |
|
\fB\-c\fR class |
|
Set the query class. |
|
Possible values for class are |
|
ANY, CHAOS, HS and IN (default). |
|
.TP |
|
\fB\-d\fR |
|
Print some extra debugging output. |
|
.TP |
|
\fB\-f\fR flag |
|
Add a behavior control flag. |
|
Possible values for flag are |
|
igntc - ignore to query in TCP to get truncated UDP answer, |
|
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. |
|
.TP |
|
\fB\-h\fR, \fB\-?\fR |
|
Display this help and exit. |
|
.TP |
|
\fB\-s\fR 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. |
|
.TP |
|
\fB\-t\fR type |
|
Query records of specified type. |
|
Possible values for type are |
|
A (default), AAAA, AFSDB, ANY, AXFR, CNAME, GPOS, HINFO, ISDN, KEY, LOC, MAILA, |
|
MAILB, MB, MD, MF, MG, MINFO, MR, MX, NAPTR, NS, NSAP, NSAP_PTR, NULL, |
|
PTR, PX, RP, RT, SIG, SOA, SRV, TXT, URI, WKS and X25. |
|
.TP |
|
\fB\-T\fR port |
|
Connect to the specified TCP port of DNS server. |
|
.TP |
|
\fB\-U\fR port |
|
Connect to the specified UDP port of DNS server. |
|
.TP |
|
\fB\-x\fR |
|
For an IPv4 \fB-t PTR a.b.c.d\fR lookup, query for |
|
.br |
|
\fBd.c.b.a.in-addr.arpa.\fR |
|
This more often gives correct names in the \fBANSWER\fR. |
|
.br |
|
For an IPv6 \fB-t PTR addr\fR lookup, query for \fBa.b.c....z.IP6.ARPA.\fR |
|
.TP |
|
\fB\-xx\fR |
|
As for \fB-x\fR and an IPv6 address, compact \fBa.b.c....z.IP6.ARPA.\fR into a RFC-2673 bit-string. |
|
This compacted \fBbit-string\fR form is not supported by many DNS-servers. |
