What happens if you point two CNAMEs at each other? Not much, really (alexanderell.is)

Played a bit around with this a few years back. Made an endless chain of CNAMEs to see how resolvers would handle it. Turned that nothing (bad) happened as the resolvers gave up after a while

Disappointing. I would have thought that doing this would result in them spinning around each other at the speed of light and then like two black holes colliding, sending an explosive shockwave through the Internet.

Sorry to hear that not much happens. Nothing cool ever works out the way you hope it might.

Don't forget to add a dot at the end of the line to make it work.
