IP hopping is simply using one set of IP addresses today, and next week you use new ones. ISPs might throw you into the category of Snowshoeing or Waterfalling. If for some reason you have to change your IPs, make sure they get warmed up properly, by relaying only a few mails per day through them. It takes a very long time to build a proper reputation for IPs.
