Ordinary users should not change their IP address with every request.
Spiders might do this, but they should be recognised by the Robot*
directives.

Users who use a proxy cluster might present themselves from a different
IP address every now and again.  Similarly, Also, if a user's ISP has a
weird DHCP setup then it might give the user a new IP address, rather
than renew the existing lease, but you shouldn't see that very often
in a normal browsing session.

You can modify Interchange's IP qualification rules with the following
directives:
