DNS spec doesn't support CNAME on the Apex record (ex your domain sans www). Alias isn't commonly supported by a lot of services yet either.

- majewsky 9y agoI saw this as well when using a self-owned domain with Github Pages. Any idea why the spec forbids it?

- bluejekyll 9y agoIt's mostly due to ambiguity. Think of it like a directory, you can't have a file with the same name as a directory in a path, because operations on that name and path become ambiguous. Zone SOAs are very much like directories on a filesystem.
- ThePhysicist 9y agoI think with Cloudflare it's possible, at least I'm pretty sure I did it with sites before using the "@" record (I could be wrong of course).
- ShakataGaNai 9y agoYes. Cloudflare does allow ALIAS style records. But in the case of Cloudflare you're actually changing your DNS over to their system. The original submission was about just making two changes to whatever the existing DNS server was you had.
