Just to followup, if one looks at stats for the K-root server, operated by RIPE:


.local is more popular than .org, and .home is more popular than .de,
.pl, .it, .uk and other large ccTLDs. .lan is more popular than .ca or
.jp, and .wpad is more popular than .dk.

That's a huge amount of traffic, more than .cm (which doesn't make the
top lists). The need to take preemptive action is evident.
