Scan of DNSSEC signed delegations for all top level domains

3rd of February 2017 / bert.hubert@powerdns.com / @powerdns_bert

Context & tooling used: https://ds9a.nl/hypernsec3/

A quick not too precise (+-10%) scan of number of signed records in various top-level zones. Note that NSEC estimations are particularly rough. Raw data is in zones.js.

For comparison, official numbers for some TLDs can be found on http://www.statdns.com/. Even more numbers are on http://rick.eng.br/dnssecstat/.
