dew4au writes "A reader over at SANS Internet Storm Center pointed out a certified letter his organization received from ARIN. The letter notes that all IPv4 space will be depleted within two years and outlines new requirements for address applications. New submissions will require an attestation of accuracy from an organizational officer. It also advises organizations to start addressing publicly accessible assets with IPv6. Is ARIN hoping to scare companies into action with the specter of scarce resources? This may be what's needed to spur adoption since there appears to be no business case for IPv6 deployment."
