@fribbledom hmm, someone brought this up in my computer networking class and the professor said... it wasn't important??


It is a problem for anyone who cares about DNS and/or security. Maybe your professor doesn't belong to either group :thaenkin:

@fribbledom @ibagail Even regardless of security its just a really fuarking dumb thing to do, AND its been implemented poorly and inconsistently.

If I have layer01.www.www.m.layer02.www.p7.co.nz that will get shortened to layer01.layer02.p7.co.nz

@tA @fribbledom yeah i read the thread and that shit looks UH OH

@tA @fribbledom
Why does the presence or absence of the www make a difference? Are there websites not on the web?

@DialMforMara @ibagail @tA

The same domain name with and without "www." can technically point to two different internet addresses. It's not often the case, but when it's the case this becomes confusing and potentially misleading from a security perspective.

@fribbledom @ibagail @tA That's as far as I understood before you began explaining. Why is this allowed?

@DialMforMara @fribbledom @ibagail @tA Same reason that anke.tumblr.com and mara.tumblr.com are allowed to be different: They have different subdomains. One is 'www', one is '' (empty string)


@Anke @fribbledom @ibagail @tA So the problem is that www does not have the privileged status that everyone thinks it does.

I have a feeling it would be easier to change that fact than to change public awareness. How do we go about it?

@DialMforMara hmm, i never thought about it like that, but I guess you're right- there is a public misconception about the meaning of subdomains!
In Google's opinion, the www. subdomain is "optional" or "implied", which is why this whole thing is happening, apparently.

@ibagail it's the vermiform appendix of the internet

it even looks vermiform: www
