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
