If the IP address is changing that frequently, presumably the clients
are using a DNS name of some sort to get to the server? You could just
redirect to that. 

In fact, with mod_rewrite you can rewrite to "whatever they came in
requesting (%{SERVER_NAME}) but via SSL" with something like this:

    RewriteEngine On
    RewriteCond %{HTTPS} !=on
    RewriteRule ^/(.*)$ https://%{SERVER_NAME}/$1 [R,L]

${SERVER_NAME} is simply the content of the host header; if the
client's requested an IP address than I think it'll be populated with
that.
