IP addresses may be legimately shared in a number of circumstances:

• AOL uses a limited number of proxies for all their users
• college and university students typically have shared IP addresses
• in countries with limited internet access users will commonly share IP addresses
• etc.

That's why barring according to IP address isn't a great idea.
