Preview site without DNS setup

You can put as many host names as you like in a hosts file entry, e.g.:

99.88.77.165    foo.example.com bar.example.org baz.example.net

All three of those host names would then resolve to 99.88.77.165. Your web server configuration would decide which site to serve based on the "Host:" line sent by the web browser. For example, requesting http://baz.example.net/home/admin/web/ would cause the browser to send baz.example.net in the Host: field.

Thanks Vance,

Editing the vhosts file on Linode was the missing piece.
