Meanwhile: one of the major mobile network in my country announced cisco collab/ipv6 ~5 years ago, but still doesn't provide v6, just v4 CGNAT.

Personal web server running dual stack since early 2010s currently sees 18-20% v6 traffic. When split by type, counting only mobile users it reaches 30% at peak.

Bot/crawler traffic is ironically 100% v4.

Meanwhile: enabled h3 in september last year for the fun of it, instantly at >40% traffic by request count, passing 50% since the beginning of the year, h2 accounting almost all the remaining traffic and plain ssl/http requests <1% being just bots.

Maybe the best anti-scraper/LLM protection is going IPv6 only. I'd do that on my website, but I'm afraid some clients might not connect.
