IPv6 Usage Reaches Historic 50% Across Google Services

IPv6 usage [1]briefly reached 50% across Google services for the first time , marking a major milestone for a protocol created in 1998 to solve IPv4's address shortage. Tom's Hardware reports:
> [...] IPv6 was dismissed early on as a headache-inducing, hard-to-implement complication that would hardly ever gain any traction -- despite offering 2^128 possible numbers, solving all network number assignments in one fell swoop. That changed over time by force of necessity, and [2]Google's tracking graph shows that for a brief moment in time on March 28, 50% of worldwide users accessed the service over an IPv6 connection, marking a historic first. [3]APNIC's stats show that the protocol is in use by 43% of the world, with Asia and the Americas inching ever close to those 50%. Cloudflare, meanwhile, shows that 40% of traffic is done in IPv6, an actually impressive figure if you consider it's measuring actual transferred packets rather than just counting addresses.

> The tried-and-true IPv4 and its well-known 123.456.789.123 format from 1980 offers ~4.3 billion addresses in theory, and around 3.7 billion in practice. That always sounded like a lot, but nobody could have predicted just how rapid the explosion of the Internet would be. IANA, the entity controlling the North-American IPv4 space, ran out of IPv4 addresses around 2011, while its European equivalent RIPE NCC could spare no more four-octet addresses nearly seven years ago in 2019. Asian, African, and Latin-American IP registries equally ran out during that timeframe.
