Thanks again.  I don't think much action has followed.  I see 512-bit
RSA DNSKEYs from:

#domains  primary nameserver
--------  ------------------
   7535  ns1.gratisdns.dk

and a somewhat smaller, but still significant counts at:

#domains  primary nameserver
--------  ------------------
   3375  ns1.mijnhostingpartner.nl
    537  ns1.zeptor.nl
    501  ns1.dnsimple.com
     93  dns1.easydns.com
     61  ns.iinfo.cz

It would good to get all 512-bit DNSKEYs upgraded.
