Everything you've suggested requires all networks to cooperate/spend extra time and money, or that no one makes an exploitable protocol in the future (as likely as humans never making mistakes). If you can already get all networks to cooperate/spend extra time and money, then you can make them do BCP38 which would be a more complete solution. > In addition to your mistaken impression of my inexperience in the filed you are also mistaken that the information I posted is "off a random website". The information is from Akamai's State of the Internet site and represents Akamai's "real-time 24-hour global attack data: sources, targets, and types of attacks". It is linked to directly from Prolexic's home page. Though, I'm sure as an expert you knew that. And all of this doesn't disprove anything I said. That website is a marketing piece made for laymen such as yourself. The fact that you are categorizing those attack vectors as seperate problems instead of being in the same class proves what I claim.
