Documentation is a vital part of the network industry. It allows us to quickly and correctly adapt new technologies, and spread best common practices. Unfortunately documentation is riddled with IP space that's actually globally routed ( An unsuspecting network operator can copy/paste configuration, and inadvertently hijack the IPs, or send trash to the actual prefix operator (Cloudflare).

In this short talk I'll talk about one such event we've seen, causing head scratching, and hopefully make some more operators aware of the documentation prefixes.
