CNAME was *never* the right answer for doing application > level indirection in HTTP space. Throw some shade at SMTP as well, if I send mail to jared@cname.nether.net and that pointed to @nether.net it would end up as @nether.net in the messages :-) Part of it is just the human nature of how we debug things. I can speak HTTP because it was easy to type telnet localhost 80. These days I have to do the same thing but with openssl s_client etc.. If these methods to debug weren’t so hard, it would have gone much further to helping. Developers/users want easy debugging steps and what we give them is things like the ednscomp tool, which is technically awesome but not very user friendly. Instead of doing a dig on the port test tool, it’s much easier to visit https://cmdns.dev.dns-oarc.net/ instead. I also may not have dig on my phone.. (ok, well I do). I think a lot can be learned from how Apple (as an example) made simpler APIs to do connections vs doing gethostbyname()^wgetaddrinfo(). It makes it easier to build tools if you don’t have to learn how to do all these things. I really like Unix, the simplicity of many calls in C, but sometimes hiding the internal layers is what’s needed. This is why https://developer.apple.com/documentation/foundation/nsurlconnection?changes=_2 is a thing. This is why folks are doing what tjw says, “meh, go to route53 because it does what I expect”. This doesn’t mean the internals aren’t important, but many application developers and end-users can’t be expected to know/care about how a CNAME at apex differs from an A record w/ redirector. One thing that SMTP got right was MX records, so it’s easier to say “go over here”. While I’m sure someone will say that HTTP should have it’s own (eg: SRV) but the barn door is still open, etc.. - jared
