ldns-walk

ldns-walk(1)						      General Commands Manual						      ldns-walk(1)

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
