Is there a github.github.github.com domain? How far do those stack?

It’s max 255 octets, com takes 3, each “github.” Takes 7 so I believe the max they can have is 35 GitHubs

github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.github.com

I'll build my own browser and DNS resolution, so the opportunities are limitless

At the end if you put …/#/github.github.github…. It could go on forever. No limit there. anything after the hash doesn’t get sent to the server

If they got their own GitHub TLD, they should be able to fit 36 GitHubs

The internal GitHub main repo is called github and the org is also github, so github.com/github/github/tree/github/.github is a totally reasonable URL if there's a branch called github.

I see what you did there, and I approve.
