is equivalent to http://to/ The site is simply hosted on the top level domain to.
The same could be hosted at http://com/ if whoever is in charge of com wanted to. You typically see it with the . like http://to./ so it doesn't resolve to a local machine named to or get resolved by the browser incorrectly.
The . is superfluous—the actual domain is http://to/, but Firefox, at the very least, converts that to http://www.to.com/, and that's not what we're going for at all. Additional . characters on each side don't mean anything, and appending a . lets the browser know that that's all we want. http://.to/ should also work, but Firefox seems to want to point it to http://www.to/.
.to is a top-level domain that belongs to Tonga, and the company in charge of allocating domain names has created one with no second-level domain, which is perfectly legal.

Are you referring to the Tonga top-level domain? If so, it's just another TLD for a specific country.
我怀疑您是在询问以下国家/地区的
.toccTLD汤加。I suspect that you're asking about the
.toccTLD for the country of Tonga.
