.to is the Internet country code top-level domain (ccTLD) of the island kingdom of Tonga.

The government of Tonga sells domains in its ccTLD to any interested party. Because to is a common English preposition, it became popular to craft memorable URLs called domain hacks that take advantage of this, such as Daniel Bernstein's website, URL shortening services such as, uploading services like (which means in Czech language) and BitTorrent websites.

The .to ccTLD is administered by the Center (Tonic).

The city of Toronto, in Ontario, Canada, has TO (pronounced Tee-Oh) as its nickname. Therefore, the .to extension is used by some small businesses located in Toronto, despite Canada's own .ca.

As the .to domains are paid for, all normal DNS operations are possible and registered sites are not required to display ads on behalf of the registrar. Some domains are free, like, but only to real Tongan educational institutions. At this moment businesses registered in Tonga can also get free domains. People who sell on .to domains can claim a bonus.

.to is one of the few ccTLDs that (officially) does not maintain a (public) WHOIS database providing registrant information.
