This is not true if you control the IP address space and the routers around it. I mention this merely because "IP addresses have never been good authenticators" or the like is becoming a truism. For ISPs with good source filtering in place then IP addresses ARE good first level authenticators (e.g. filter lists on management ports). Note: I say FIRST level authenticators; IP addresses are obviously not suitable as the whole authentication process. Sending confirmation E-mail addresses aren't that much better. And blacklists will just continue to grow longer.
