I'm assuming that access to dropbox is blocked somewhere upstream of you
via a filter of some kind. With that in mind...
$dig dropbox.com aaaa

Considering that dropbox doesn't appear to have an IPv6 side, your only
option that I can think of is to find a IPv6 to IPv4 proxy, which I
don't think exists, or a 'standard' IPv4 proxy.
