Not possible - that's not the way IP addresses work.
If I am on dial-up, every time I connect I am assigned a different IP from the pool of IP's owned by my ISP. My ISP has about 200,000 customers, so it's likely they have a block of around 64,000 IP addresses. In actual fact, I'm on DSL. My router "leases" an IP by the hour. It usually gets the same one back, but if it disconnects, (which it sometimes does if I answer the phone) it usually reconnects to a different IP address.
For the same reason you cannot block an IP address to stop a vandal who is not logged in. And banning an ISP's entire IP block prevents their entire customer pase from contributing to Wikipedia.
