Technically, it did take some planning, but not all that many resources.
It required that there be an IP interconnect range with enough available
IPs between at least two adjacent routers, and DNS control of the reverse
DNS domain name, which would normally come with the IP range allocation in
moderately sized commercial and carrier grade spaces.

I'm not belittling this, because it's both creative and fun, but it's not a
particularly *difficult* task.  There's work involved, but not many

The bad.horse example was run in 16 IP addresses in the
range, which is part of a larger allocation ( to
"Sandwich.net," a hosting and Internet services provider in Minneapolis.
It also required getting the 'bad.horse' domain name registration from the
new .HORSE registry operated by minds+machines (www.nic.horse).

I don't see how to get the date/time from the link provided by Bill Baker,
which is what I'd need to look up historical range allocation data, but the
address space involved there has been allocated to Epik networks in Toronto
(epikip.net) since 2010... which makes it seem likely that they were the
ones behind the New Hope runner.
