Including the period?

no

Actually, it shouldn't matter. A trailing dot in a hostname signifies a fully-qualified domain name, rather than a relative domain name. Without the dot the router's dns service could technically return 'cbc.ca.some.othersite.net.' as the FQDN.

They meant the period in the middle (as in, "can you type the full thing, including the period in the middle, with one hand?"). I read it the same way as you did, initially.

I did, too, and I was the original replyer (is that a word?). But, if you visit cbc.ca once, you can do it with one hand in the future as it's the first option in the autocomplete dropdown.
