At DNS-OARC in in Montreal, October 2015, the Verisign people pointed out
that J-root's old IP address is still active, 13 years after the new
address was published, and it gets 100-200 qps, if I recall correctly.

No one was really sure what DNS servers were out there using 13-year old
root hints files, but they are out there, sending queries.

Maybe IPv6 devices will be updated more often than IPv4 devices. Maybe?
