Answer 1

The other answers are fine, but bear in mind that many DNS registrations are protected by anonymization services, and that many sites are also hosted by providers in countries other than the one where the site's owner is.

example.com could be physically hosted on an American ISP's server, DNS provided by a Canadian company, and the site's owning company could be in Lesotho. You just can't tell these days.
