We have been enforcing delegation requirements on our registrants for
over 25 years (from the beginning of the .is registry - modelled after
.fr at the time) and have observed considerable improvement. Although
we are a very small registry we do believe our methods would
scale easily to larger registries.
We feel strongly that as a registry we must serve not only the
registrants (our direct customers) but also those that use
DNS to look up these registrant's domains.
After delegation all domains are checked once a month and with
the current setup we are checking about 1 domain per second
(thus could scale to ~2M domains with the same setup.) If the domain
no longer satisfies the .is requirements, it is tested weekly
for eight weeks and progressively more of the domain's contacts
informed of the problem (starting with the domain's zone contact
which is assumed to be the operator of the domain's master nameserver).
If the problem persists for over 8 weeks, the delegation is removed.
We have found that over the years, more and more of our registrants
(or their zone contacts) are grateful for the notification
(as opposed to annoyed) and most have no problem fixing the faults
with their authoritative NS setup or moving their DNS hosting services
