# If IPv4 Were Land - World Map Redrawn by IPv4 Addresses Source: [https://iptrust.co/blog/if-ipv4-were-land](https://iptrust.co/blog/if-ipv4-were-land) Tables include countries with at least 100,000 IPv4 addresses and 20,000 km² of land\. Method: area as IPv4 = \(country's IPv4 addresses ÷ world IPv4 addresses\) × world land area\. Land area is computed from the map geometry, so it's the 1:110m Natural Earth outline, not official figures\. Antarctica excluded\. About 70 small territories have no outline at this resolution and are left out \(around 52M addresses, mostly Hong Kong, Singapore and Mauritius\)\. IPv4 counts come from the IP Trust geolocation database, October 2026\.

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

Lobsters Hottest

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

Lobsters Hottest

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

Hacker News Top

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

Hacker News Top

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.
