> sometimes All fully-qualified domain names end with a dot. The dot is effectively the label for the DNS root. Most tools (e.g. browsers) automatically assume a trailing dot. [Edit] Interestingly, if I add a dot to this URL, after the domain-name, it works, and I get essentially the same content; but the styling is quite a bit different. I imagine it must be to do with the way stylesheets are referenced from HTML. [Edit-2] I deprecate the use of the term "DNS root" to refer to the domains .com, .net, .org etc. These are top-level domains, not "roots". There is a single root, and it's name is dot.
