A look at something you've just used, DNS! • Note in my demo I request just the child part of the FQDN that the name server is authoritative for to avoid any cached entries return the final resolution too soon but as I said in the whiteboard the full FQDN is asked each time and you just get referred to the next nameserver down. • 👂 I have manually updated the captions to be as accurate as possible. Enable the subtitles and from there you can translate to your native language via the auto-translate feature in settings! • YouTube Captions and Auto Translate Q... for a demo of using this feature. • 🔎 Looking for content on a particular topic?
