You can use iodine and do a delegation from a real domain: It encodes packets in subdomains of your domain (and decodes them with a special DNS server). It is not fast.

I like to use SNI with e.g. pagead2.googlesyndication.com and www.googletagmanager.com because a lot of captive portals put ads on them, and I it on a google cloud instance since they own the IP.

I've gotten this to work, but it's just so slow that it's not worth it.

Those are great domains for this kinda thing! Thanks for the idea
