A new data visualization reassigns country sizes based on each nation's share of global IPv4 address space rather than physical geography, using October 2026 figures from the IP Trust geolocation database. The method scales each country's area to (its IPv4 count ÷ world IPv4 total) × world land area, drawing outlines from the 1:110m Natural Earth map and excluding Antarctica and roughly 70 small territories too small to render at that resolution.

IPv4's 32-bit addressing scheme, which created about 4.3 billion addresses, ran dry years ago, with North America's allocation exhausted in 2015. ISPs have papered over the shortage using carrier-grade NAT, which shares public addresses among groups of customers but can break peer-to-peer connections like online gaming. IPv6, standardized in 1995 with 340 undecillion possible addresses, is meant to solve this permanently but currently coexists with IPv4 rather than replacing it, with Google measuring global IPv6 usage at just under 51 percent.

A networking blog post describes hands-on testing of RFC8950, a BGP extension that allows IPv4 routes to be advertised with IPv6 next-hops over IPv6-only sessions. The post notes the standard is already supported in Juniper JunOS, Cisco IOS XR, Nokia SR OS, Mikrotik, Huawei, BIRD and FRR, and includes a demo lab setup to illustrate it.

Network Address Translation, introduced in RFC 1631 in 1994 as a stopgap for IP address depletion, let multiple devices share a single public IP by rewriting packet headers. That fix, paired with restrictive ISPs and CGNAT, made it hard for ordinary devices to act as servers, pushing users toward centralized cloud services instead of direct peer-to-peer connections.
