IPv7: Identity-Centric Network Protocol for Security, Proxy Mitigation, and Operability

This document specifies a network-layer protocol, IPv7, that extends the Internet Protocol model with an identity-carrying address form and an origin-validation mechanism intended to mitigate abuse of residential proxy infrastructure. IPv7 replaces purely numerical source addressing with a hierarchical identity string and a Variable- Length Identity Block (VLIB) that carries an Ephemeral Identity Token (EIT), provider and tenant identifiers, role/policy signalling, and an Origin Signature verifiable by the originating provider. The protocol enables routers to apply policy and reputation signals at the network layer while limiting disclosure of a subscriber's long- term identity to intermediate systems. This document addresses growing security challenges in Internet-connected devices (IoT), including smart TVs, appliances, and other residential endpoints that are vulnerable to residential proxy exploitation and botnet infection.
