The DNSSEC-signed .com domain was put into operation yesterday. So, how
many .com zones have been DNSSEC-signed? Duanne Wessels created a DNSSEC
scoreboard where we can keep track of the number of signed .com, .net (and
.edu) zones. At the time of this writing it looks like this:
Another, maybe more interesting, diagram which shows delegations over time is
count-trace.png. Considering .com has round about 90,000,000 (ninety
million) domains, we have only just started. :-)
