Indeed, some of the most important and most successful nodes on the Internet rely very heavily on various DNS tricks, and without them wouldn't be operating. If we are serious about "making the Internet better", surely we ought to have an opinion on how to offer (as well as can be achieved given other strictures) the functionality that is in fact ubiquitous. <snip> Either those who understand how the DNS works will document what to do, or else people who have no clue will make more "improvements". In this bucket you can put in all the 'CNAMEs at Zone Origin" work done by both the CDN vendors and the commercial DNS vendors in this space. I was thinking once the Charter had been finished being blessed, I would put my toe in that water and see what lies beneath the surface. On a personal level I'd love to see some work done on "CNAMEs at Zone Origin" as the issue just bit me with one of my own sites. For a good number of years I've been giving out just the domain name as the web address and that worked fine with me providing an A and AAAA record pointing over to the hosting provider (all DNSSEC-signed, of course). Then recently the hosting provider got slammed with a massive DDoS attack and in fighting off that attack they put up a CDN in front of all the hosted web sites. We customers were then told to ensure we were using CNAMEs instead of direct addresses... for me this has meant unfortunately having to switch to using "www.<domainname>" for that site and setting the CNAME there. I'm still working out which of the various "DNS tricks" from different providers that I'll have to use to get the raw domain name to point correctly over to the web hosting provider.... and given that I have many years of posts out there with links to the raw domain name this is kind of important to me. For some time now I've been seeing in the marketing/communication space an increasing usage of dropping the "www" and just promoting the raw domain name. I think with the many hundreds of newgTLDs coming out we'll probably see people there seeking to use only the domain name for their website. And many of them will want to use hosting providers or CDNs where the desired configuration is to point a CNAME over to the hosting/CDN provider.... which leaves them stuck - or resorting to "DNS tricks" - if they want to use the zone name itself as their web site address. So yes, I think this is very definitely a current operational problem that needs to be worked on.
