The way you are using "www." and "." is incorrect. The dot isn't part of the local hostname "www". It is a separator or delimiter for the textual elements in the domain name. "Redirecting from (or to) ." is a weird and as far as I know completely wrong way to talk about redirecting from or to the domain name one level up in the hierarchy. The only time a dot plays any role in a domain name (other than that of a simple separator) is when it's used at the end of the fully qualified domain name.
- Avamander 7y agoWhat if I'm talking about redirecting an entire TLD "www" to ""? Obviously it's a separator, I just found writing "" and "www" too weird. Not to mention that in this context where you're not really a recursive DNS resolver it really doesn't matter how one specifies the existence or lack of it of a subdomain. In addition to that some things use "@" (instead of the dot I used).
- notfashion 7y agoWhether it feels weird or not, the hostname label is "www". The hostname-as-tld example is sort of against the rules: https://serverfault.com/questions/907226/is-it-possible-to-create-an-a-record-for-a-global-tld https://serverfault.com/questions/907226/is-it-possible-to-c... Either way, "." by itself can only meaningfully refer to the root, not some arbitrary enclosing domain name. There is no way you will convince me that using "." as a shorthand for "parent domain" is a good idea, for that and all the other reasons.
