Yah, that's right, but Tokihiko's numbers also sound about right on the average, as in, a personal router tends to get reset within a week's time. If nothing else because the ISP drops out temporarily, or due to line interference.

Single IP blocks can still help, as some will not reset the router, or may share one and not be able to reset it, but the block should only be on the order of days. For especially destructive vandalism where the same abuse is seen on different IPs in same range, range block is reasonable even though it blocks innocent IPs as well, but for that reason, it should also be temporary, say a week.
