One of the more rewarding parts of running a niche tool is finding out other people have built tutorials around it for audiences I'd never reach myself.
William Gregoire put together a French-language walkthrough of using ASN-based filtering inside FortiGate, episode 6 of his FortiGate meilleures pratiques (FortiGate best practices) series. The video pulls prefix data straight from asn.ipinfo.app and shows how to feed it into FortiGate rules — exactly the pattern the /guides/ page covers in English for other platforms (iptables, nginx, pfSense), but tailored to FortiOS workflow and the kind of policy decisions that come up in real customer networks.

If you're a francophone network engineer running FortiGate gear — or you just want to see how someone else thinks about ASN-level filtering on the platform — this is well worth the watch. William's whole channel is in the same vein: practical FortiGate configuration walkthroughs from someone who actually administers the gear day-to-day.
I'd love to add more walkthroughs to the community section of the guides page, in any language. If you've built tooling, scripts, videos, or written posts that use the asn.ipinfo.app data, drop a line and I'll add a card.
