Chase any signatures a the jelte.nlnetlab.nl domain.
drill -TDI www.example.com
Do a DNSSEC (-D) trace (-T) from the rootservers down to www.example.com.
drill -s dnskey jelte.nlnetlabs.nl
Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY record also print the DS record.

OPTIONS

-D, --dnssec
Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG, DS and NSEC) this is automaticly enabled.
-S, --sigchase
Chase the signature(s) of 'name' to a known key or as high up in the tree as possible.
-T, --trace
Trace name from the root down. When using this option the @server and the type arguments are not used.
-V, --verbose
Be more verbose. Enable once for more messages on the screen. Enable twice for a hexdump of the packets sent.
