A Farewell to ARPs: IPv4 Service on IPv6-Only Networks
This article presents an IETF draft proposal to eliminate ARP and IPv4 subnets on IPv6-only networks, allowing IPv4 to run as a pure /32 service over IPv6 infrastructure without translation or tunnelling, addressing operational pain points like ARP storms and IPv4 address scarcity.
Hacking the Go compiler to efficiently map IPv4 to IPv6
Vincent Bernat explores how to efficiently map IPv4 addresses to IPv6 in Go's netip.Addr, comparing a standard library addition, an unsafe helper, and hacking the Go compiler to optimize the netip.AddrFrom16(ip.As16()) pattern that maintainers prefer.
Show HN: We Implemented the IPv8 Internet-Draft in Linux, Libc, and BGP
The team at goonhost.rocks implemented the IPv8 Internet-Draft across the Linux kernel, Musl libc, iproute2, FRRouting, and a Go zone server, then deployed it on a 10-node multi-AS testbed with 112k+ routes. It works in isolated lab conditions but breaks in real-world scenarios.
RPKI Now Protects 70% of Internet Routes, Up from 54% a Year Ago
RPKI-validated routes rose from 54% to over 70% of global internet routes in a year, driven largely by China's jump to 83% IPv4 coverage. Analysis shows invalid routes now barely propagate, reaching only about two BGP vantage points on average, confirming RPKI effectively blocks hijacks and misorigination.

Iwo Kadziela created a method to generate a credible ASCII world map using only 445 bytes of data by leveraging deflate compression and JavaScript's DecompressionStream API.
