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'. Otherwise 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 results are validated, but that they can be validated. OPTIONS
-i option enables a mode where the working IP addresses are printed after another, with no other explanations, and if none work or no IP addresses 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. AUTHOR

ldns-walk - Retrieve the contents of a DNSSEC signed zone SYNOPSIS
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
-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. @ nameserver Send the queries to this nameserver. BUGS
The full zone walk function is not complete yet, it does not correctly print delegation records AUTHOR
