nslookup alpine-usa.com

Modern web browsers, if you enter http://alpine-usa.com/ will check for that
exact name first, then if it's not found, as in this case, it will do
another query for www.alpine-usa.com.  That's why the first URL works
properly even though there's no address record for that name, and why when
the page finishes loading Firefox displays "http://www.alpine-usa.com/" in
the address box.

Check a tcpdump or Wireshark trace to see this behavior first-hand.

  There is no A record associated with <alpine-usa.com.>.  There's nothing
technically wrong with that, but it's customary to give the IP address of
your web server.  That will let people type "alpine-usa.com" into any web
browser and still get your web site.
This won't cause timeouts or other errors, though.
