A Farewell to ARPs: IPv4 Service on IPv6-Only Networks
Summary
The article advocates eliminating ARP and IPv4 subnets on IPv6-only networks by introducing a dedicated IPv4 service over IPv6, using a sentinel IPv4 address (192.0.0.11) and host-side resolution to avoid ARP and subnetting. It describes current production workarounds by large providers, discusses why changing DHCPv4 is impractical, and aligns the proposal with RFCs and IETF drafts to achieve a single-stack architecture for dual-stack endpoints.
