How to tell if WordPress is hosted on WP servers or not?

Hey guys,

How can I determine if a WordPress blog is being hosted on a company’s own webhost server, or if it is hosted on WordPress’s server? The company’s blog’s address is, so it isn’t on the WordPress domain. Does this mean it is being hosted with that company’s webhost, as opposed to WordPress’s servers?

Also, I clicked a picture in one of the blog entries and it brought me to … Is this another sign that it is indeed hosted on that company’s own webhost server?


Thanks a lot guys
