The .DE domain extension is commonly used in Germany.
It's like a digital address for websites, emails, and other online stuff.
If you see a website ending in .DE, it's likely from Germany.
It's popular because it shows you're part of the German online community.
The history of the .DE domain's origins
The .DE domain extension started back in 1986 when the internet was just starting to grow.
It was one of the first country-code top-level domains (ccTLDs) created, and it's been around ever since.
Germany adopted it early on, and now it's one of the most recognized domain extensions worldwide.
