That depends on whether their IP is dynamic or static. If it's static, it won't change, but since you were assigned an IP used by many users, you can guess yours is most likely dynamic. Unfortunately, dynamic IPs are always an issue when it comes to vandalism along with proxies which also allow users to change their IPs to get around bans, but admins usually deal with it on a case by case basis.
