A Farewell to ARPs: IPv4 Service on IPv6-Only Networks

# Summary An IETF proposal (draft-vanmook-intarea-ipv6-resolved-gateway) aims to eliminate the need for parallel IPv4 subnets and ARP protocols on IPv6-only networks, allowing IPv4 to function as a service over pure IPv6 infrastructure without translation or tunneling. Currently, most operators maintain dual-stack networks despite having IPv6-only capabilities, creating operational burdens including ARP scalability issues, high costs for IPv4 addresses, and significant management overhead.
