Hinzugefügt: 2026-06-03

[00:00:00]What actually happens when you visit a website? You type youtube.com into your browser, but your computer has no idea what youtube.com is.

[00:00:10]>> Huh?

[00:00:11]>> Computers only understand numbers. Every website actually has an IP address, so who does the translation? DNS, domain name system, the internet's phone book.

[00:00:23]You type youtube.com and DNS instantly translates that name into an IP address behind the scenes. The whole process happens in under 0.1 seconds.

[00:00:34]Without DNS, you'd have to memorize a string of numbers for every single website you visit. DNS is the invisible hero that makes the internet usable for humans.
