To hopefully awaken and further inform the discussion around the ANAME and HTTP draft specifications that have been put forward, I've done some further analysis across the Alexa top 1 million domains - my initial findings are available at https://thpts.github.io/a_or_cname/ . A brief summary of what I have found across the entire dataset: * 51% of www records return an A record * 47% of www records return a CNAME * 64% of those point www back to apex (i.e. www.example.com. IN CNAME example.com.) * 17 www records are DNAME Any feedback, corrections, and suggestions would be greatly appreciated.

What I found is that approximately 44% returned CNAME records, 56% returning A records. Code is https://gist.github.com/thpts/eb5cec361867170a0ffd6ede136c6649 here if anyone wishes to look. Regards * I realise that I could have added AAAA. My presumption is that the top 10k websites are not v6 only and at least have an A record in place. *From: *DNSOP <dnsop-bounces@ietf.org <mailto:dnsop-bounces@ietf.org>> on behalf of Olli Vanhoja <olli@zeit.co <mailto:olli@zeit.co>> *Date: *Tuesday, 6 November 2018 at 08:24 *To: *<dnsop@ietf.org <mailto:dnsop@ietf.org>> *Subject: *Re: [DNSOP] Fundamental ANAME problems In fact if you look at the DNS records some big Internet companies they rarely use CNAMEs for www but instead you'll see an A record, that might be even backed by a proprietary ANAME solution.
