NAME

       ldns-walk - Retrieve the contents of a DNSSEC signed zone

SYNOPSIS

       ldns-walk [ OPTION ] ZONE

DESCRIPTION

       ldns-walk  is used to retrieve the contents of a DNSSEC signed zone.  It does this through
       NSEC-walking (following the chain of NSEC records) and 'guessing'  the  next  non-existent
       owner name for each NSEC.

       Note  that  it  might  get  stuck  on  some  wildcard  records when used through a caching
       forwarder. This problem can be  circumvented  by  querying  the  authoritative  nameserver
       directly (with the @ argument).

       Of course the nameserver that is used must be DNSSEC-aware.

OPTIONS

       -4     Use only IPv4.

       -6     Use only IPv6.

       -f     Do  a  'full'  zone walk; by default, ldns-walk will only show the names, and types
              present at those names. If this option is  given,  all  resource  records  will  be
              printed.

       -s name
              Start  the  walk  with this owner name. Useful when continuing the walk for a large
              zone.

       -v verbosity
              Verbosity level [1-5].

       @ nameserver
              Send the queries to this nameserver.

BUGS

       The full zone walk function is not complete yet, it does not  correctly  print  delegation
       records
