computer language poll: is mail.google.com a subdomain of google.com? (not a trick question, no wrong answers, please don't argue about it in the replies, I'm just curious what different people think the word "subdomain" means :) )
the ambiguity here is that mail.google.com doesn't have its own NS/SOA record. An example of a subdomain that *does* have those things is alpha.canada.ca -- it has a different authoritative DNS server than canada.ca does.
anyway I think arguing about definitions of words is super boring but I always think it's interesting when a really common technical term has multiple meanings (so far 6% of people definitely voted no to that poll! :))
if it's not obvious, the point of this is definitely not to tell you you're wrong if you voted yes (i voted yes! :))
man, some people in the replies are really focused on whether the "right" answer is "yes" or "no" and I don't get it. the point is just that different people use different definitions for the same word and that's interesting and normal and okay!
I love knowing about different possible definitions for terms because then if I'm having a discussion with someone and they use an ambiguous word, I can ask "oh, do you mean definition A or B?" and then we can pick a definition to use in our conversation
