Your reply is riddled with errors and you don't seem to actually know how the DNS protocol works at all, on the wire or otherwise. It is, firstly, impossible for "google.com" to contain a CNAME record. This would violate standards, and it's simply not done. Query or yourself; there is no CNAME at that label.
Your description of how queries work is not how queries work at all. Your entire comment is a net negative and detracts from the overall knowledge at Hacker News.

- NoZebra120vClip 3y agoThis is a disingenuous claim, because many of the comments at the linked thread indicate that it not only is a breach of the RFC requirements, but is also liable to malfunction, so any provider/software that permits it, is going to have trouble supporting it. I stand by what I said: it's impossible, and is simply not done [by anyone who cares about adhering to standards or interoperability.]
