28.5 percent of global traffic was IPv6 during 2024

2024 according to Cloudflare: Global traffic up, Google still king, US
churning out bots

Cloudflare says that global internet traffic grew by 17.2 percent this
year, with Google still the most visited internet service, while the
US was the source of over a third of global bot traffic (again).

AI bots have been in the news this year as they trawl the web for
content to train models, and Cloudflare now has a dedicated tracking
page for these. The company says that Bytespider, a crawler operated
by TikTok owner ByteDance, started high but has shown decreasing
activity through the year, while Anthropic's ClaudeBot has spiked in
activity a number of times.

Mobile device traffic accounted for about 41.3 percent of the total,
which is roughly the same as last year. This is largely split between
the Apple and Android ecosystems, with iOS on almost a third and
Android accounting for two-thirds.
