What is IPv6? (Explained like you would to your grandma)

📬 What is IPv6? (Explained like you would to your grandma)

🧩 The Internet is like a huge city…

Every house has an address, right? So the mailman knows where to deliver letters.

On the Internet, it’s the same: every device (computer, phone, printer, smart bulb…) has an IP address, which allows it to send and receive data.

📦 IPv4: the “classic” address

Until now, we’ve used IPv4, which creates addresses like:

192.168.1.1

Simple, right? But there’s a problem: IPv4 can create around 4 billion addresses… and we’re running out! Everything is connected today: fridges, TVs, watches… We need many more addresses.

🚀 IPv6: the new kind of address

That’s why IPv6 was born — a modern version that uses much longer numbers, like:

2001:0db8:85a3:0000:0000:8a2e:0370:7334

Looks complicated? A bit, but don’t worry grandma — computers understand it instantly!

Thanks to IPv6, we get:

an almost infinite number of addresses
faster performance in some cases
a more modern Internet, ready for the future

🔍 IPv4 vs IPv6 (at a glance)

Feature	IPv4	IPv6
Format	4 numbers separated by dots	8 groups of numbers and letters, with “:”
Example	192.168.0.1	2001:0db8:85a3::8a2e:0370:7334
Total addresses	Around 4 billion	Around 340 undecillion (huge number!)
Year introduced	1981	1998 (still rolling out today)
Ease of reading	Easier for humans	More complex, but managed by devices

🧠 A simple example to understand

Think of IPv4 as a phonebook with 4 billion numbers.
But now we need a number for every person, object, and toaster.
IPv6 is a giant phonebook that never runs out!

❓Fun facts

IPv6 won’t replace IPv4 right away — they’ll coexist for years.
Some websites already use IPv6. But when you browse, you don’t notice — everything works as usual.
Your smartphone probably already has an IPv6 address, even if you didn’t know!
