In principle, nothing. But you aren't their use case. At wikipedia's
page on dyn is, "Dyn was conceived as an open source, community-led
student project back by Jeremy Hitchcock, Tom Daly, Tim Wilde and
Chris Reinhardt while pursuing undergraduate studies at Worcester
Polytechnic Institute.[2] In the beginning, Dyn enabled students to
access lab computers and print documents remotely. The project quickly
outgrew its original purpose and soon gravitated towards domain name
system (DNS) services. The first iteration was a free dynamic DNS
service known as DynDNS, which allowed users to register a subdomain
that points to a computer with regularly changing IP addresses, such
as those served by many consumer-level Internet service providers. An
update client installed on the user's computer, or built into a
networked device, such as a router or webcam, keeps the hostname up to
date with its current IP address.
"This free service eventually became costly for the founders to
support. Looking to gauge interest, the project was set to be shut
down unless users were able to reach a $25,000 fundraising goal. They
ended up raising over $40,000." There's more.
So with sufficient free time and education and resources anyone could
do what dyn did. They commodified it and made it easy for
non-specialists, that's all.
