ldns-test-edns(1)	    General Commands Manual	     ldns-test-edns(1)

NAME
       ldns-test-edns -	test if	dns cache supports EDNS	and DNSSEC.

SYNOPSIS
       ldns-test-edns [	-i ] { ip }

DESCRIPTION
       ldns-test-edns  tests  a	 DNS cache and checks if it supports EDNS0 and
       DNSSEC types so that it can be used as a	dnssec-enabled DNS cache.   It
       sends  two  queries to the cache, one for the root key and one for a DS
       record.	These must succeed, the	answer must have EDNS, that  type  and
       signatures.

       If  the IP address is good for DNSSEC, it is printed with 'OK'.	Other-
       wise short description is given of the failure.	If OK  is  given,  the
       cache  should  be  good to use as a cache for a local configured	DNSSEC
       validator.

       The tool	assumes	the root is signed and Sweden is  signed.   Also,  the
       queries are sent	with the CD flag, the tool does	not check that the re-
       sults are validated, but	that they can be validated.

OPTIONS
       -i option enables a mode	where the working IP addresses are printed af-
       ter  another, with no other explanations, and if	none work or no	IP ad-
       dresses are on the input, 'off' is printed.

       ldns-test-edns takes one	or more	IP addresses, it checks	them in	 turn.
       IPv4  and  IPv6 addresses can be	given.	The exit value is for the last
       checked IP address: 0 is	OK, 1 is failure, 2 is some  sort  of  network
       failure.

       Written by the ldns team	as an example for ldns usage.
