Is IPv8 the Answer? Allocating 2.2 B Public IPs per Person

The article examines the IETF’s IPv8 draft, which proposes a 2⁶⁴‑address space that could assign roughly 2.2 billion public IPs to each individual, explains its design as an IPv4 subset with ASN‑based prefixes and built‑in security, and evaluates the significant compatibility, hardware, and adoption challenges that make widespread deployment unlikely.
