dnsget - DNS lookup utility

dnsget is a simple command-line to perform DNS lookups, similar to host(1) and dig(1).  It is useable for
       both interactive/debugging scenarious and in scripts.  The program is implemented using udns(3) library.

       By default, dnsget produces a human-readable output, similar to
              alias.example.com. CNAME www.example.com.
              www.example.com. A 192.168.1.1
              www.example.com. MX 10 mx.example.com.
       which  is just sufficient to see how a given name resolves.  Output format is controllable with -v and -q
       options -- the former increases verbosity level up to printing the whole DNS contents of all packets sent
       and received, which is suitable for debugging DNS problems, while the latter reduces  the  level,  making
       output more quiet, up to bare result with no error messages, which is good for scripts.

       dnsget - DNS lookup utility

       The following options are recognized by dnsget:

       -v     produce  more  detailed  output.   More  -v's  means  more  details will be produced.  With single
              -v,dnsget will print contents of all received DNS packets (in a readable format), while with  -vv,
              it will output all outgoing DNS packets too.

       -q     the  opposite  for  -v  --  produce  less  detailed  output.  With single -q,dnsget will only show
              (decoded) data from final DNS resource records (RR), while -qq also suppresses error messages.

       -ttype
              request record(s) of the given type type.  By default,  dnsget  will  ask  for  IPv4  address  (A)
              record,  or  for  PTR  record  if the argument in question is an IPv4 or IPv6 address.  Recognized
              types include A, AAAA, MX, TXT, CNAME, PTR, NS, SOA, ANY and others.

       -cclass
              request DNS record(s) of the given class class.  By default dnsget uses IN class.   Valid  classes
              include IN, CH, HS, ANY.

       -a     (compatibility  option).   Equivalent  to setting query type to ANY and increasing verbosity level
              (-v).

       -C     (planned)

       -x     (planned)

       -oopt,opt,...
              (may be specified several times).  Set resolver options (in a form option:value) as if  they  were
              set in $RES_OPTIONS environment variable, or set query flags:

              timeout:sec
                     Set initial query timeout to sec.

              attempts:num
                     (re)try every query num times before failing.

              udpbuf:bytes
                     set  DNS  UDP buffer size to bytes bytes.  Valid values are from 512 to 65535.  If bytes is
                     greather than 512, EDNS0 (RFC 2671) extensions will be used.

              port:num
                     Use given UDP port number num instead of the default port 53 (domain).

              aa     set AA (auth only) query bit.

              nord   do not set RD (recursion desired) query bit (set by default).

              dnssec or do
                     set DNSSEC OK (DO) query flag (dnsget does not  verify  DNSSEC  signatures,  only  displays
                     them; this is set in EDNS RR).

              cd     set CD (checking disabled) query bit.

       -nnameserver
              Use  the given nameserver(s) (may be specified more than once) instead of the default.  Using this
              option has the same same effect as $NSCACHEIP or $NAMESERVERS environment variables, with the only
              difference that only IPv4 addresses are recognized for now, and it is possible  to  specify  names
              (which will be resolved using default settings) instead of IP addresses.

       -h     print short help and exit.

       When  all  names  where resovled successefully, dnsget exits with zero exit status.  If at least one name
       was not found, dnsget will exit with  return  code  100.   If  some  other  error  occurred  during  name
       resolution, it will exit with code 99.  In case of usage or initialization error, dnsget will return 1.
