Thanks, Carsten. This is a very clear, concise, and informative article.

Given the recommendation to change NSEC3 salt values with each ZSK rollover, I 
would like to make the following suggestion for bind9 and bind10. Enhance bind9 
dnssec-keygen (and whatever the equivalent turns out to be for bind10) to 
include a random or specified salt as part of the key metadata. When the key 
activation date/time is reached for NSEC3 zones, automatically modify the 
NSEC3PARAM record and regenerate the NSEC3 chain with the new salt value.

Happy New Year to all. Jeff.
