Blocking vandals is usually better than protecting pages. If there's an IP range, then it's a different case altogether. You could always report to the VSTF, though. If the vandals are anons, you could hold a community discussion and ask staff to disable anon editing. This would, however, restrict editing by genuine anon contributors.
