The worst part of ALIAS is that traditional hosted DNS servers don't support it, as far as I can see. Usually CDN providers do handle static IP addresses at the zone apex somehow, but in this case it seems they don't.
- zimbatm 13y agoIt's not a real record in the sense that it's never sent to the client so it doesn't really matter no ? It's just a convenient way to say "return an A record or that fqdn" on the configuration side.
- namecast 13y agoYeah, you should never see anything like "IN ALIAS" in the output of dig, for example, and getaddrinfo(3) wouldn't know what to do with that sort of record. It's all internal to the authoritative NS. ...which is a bummer, because doing this adds a weird sort of black box step in the DNS resolution chain between client and server. It makes troubleshooting DNS problems not so much fun.
- zimbatm 13y agoAgreed and the option is often displayed along other real DNS records names adding to the confusion if you're not familiar with DNS systems.
