# Future

Edge notes:

* **Gemini/Google**: implement reverse-DNS verification (PTR → `*.googlebot.com|*.google.com|*.googleusercontent.com` and forward-resolve back) in your Cloudflare Worker or server; then set `google_verified_crawler=true` on the event. [Google for Developers+1](https://developers.google.com/search/docs/crawling-indexing/verifying-googlebot?utm_source=chatgpt.com)
* **Perplexity**: periodically refresh the two JSON lists; IP-only may still miss undeclared crawlers per Cloudflare’s report. [Perplexity+2The Cloudflare Blog+2](https://docs.perplexity.ai/guides/bots)
* **Claude**: only the **agent/tool egress** IPs are officially published; there is no official CIDR feed for **ClaudeBot**. [Anthropic+1](https://docs.anthropic.com/en/api/ip-addresses)
