This is a misunderstanding. In IPv4, NAT acted as a crude, non-security barrier. In IPv6's vast M2M world, security moves to the device itself.
Is "M2M Vast IP" just a marketing phrase? Partially. But behind the jargon lies a technical necessity. m2m vast ip
Let’s strip away the buzzwords and examine the reality of M2M communication, the necessity of a "vast" IP space, and where the industry stands today. This is a misunderstanding
