What is IPv6 and why do we need it?

[Graig Mellett]

IPv6 was developed to overcome the limitations of the IPv4 addressing protocol, specifically, the limited number of available IP addresses. IPv4 uses a 32-bit address space, which allows for approximately 4.3 billion unique addresses (2³²). In contrast, IPv6 uses a 128-bit address space, providing about 3.4 × 10³⁸ unique addresses.

what is mld in ipv6

[Madalitso Cheyo]

MLD in IPv6 stands for Multicast Listener Discovery. It’s essentially the IPv6 equivalent of IGMP (Internet Group Management Protocol) in IPv4. MLD helps IPv6 routers know which devices want which multicast traffic, making network communication more efficient.

why do we need, is because of Pv4 Address Exhaustion, and the growth of IOT

[TALBA YOUSSOUFA]

IPV6 is a 128-bit long Network Layer Internet Protocol. We need IPV6 to address the continued growth of connected devices on the Internet

I have an issue with this lesson. I can’t complete it because there’s no COMPLETION BUTTON only EXIT. So I’m stuck

[Oluwakemi Ajibola]

I think it marks as completed once you exit the lesson.

[TALBA YOUSSOUFA]

No it didn’t. I have even tried to reset the lesson but still stuck. I can’t advance if it doesn’t mark completed.

[Fatma Salih]

We need IPv6 mainly to accommodate the growth of the internet and its services while benefiting from the options and enhancements it offers.

[Archibolt Sebola]

-we need it to overcome the shortage of ip addresses that ipv4 is facing.

why do we need IPV6 is because of IPV4 address exhaustion, improve network efficiency ,and for better performance.

[Leonard Sighei]

IPv6 is the solution of limits of IPv4, with emergence of machine-to-machine, IoT and other technologies which requires immidiate with minimal latency, IPv6 will only provides the solution of depletion of IPv4.

[Handirove Taruvinga]

IPv6 gives us a much bigger address space using 128 bits, which means no more running out of IP addresses. We need it because the number of connected devices keeps growing, and IPv4 simply can’t keep up

[Emmanuel Amos]

Dear Dev colleagues, “IPv6 just clicked for me — and it all started with two tiny rules.”

As a software developer, I’ve longed to see my team really own IPv6. Then I discovered zero compression and its partner, leading zero suppression — and suddenly, IPv6 wasn’t scary. It was fun.

Watch this:

2001:0000:0000:0000:0000:0000:0000:0001 → 2001::1

Two rules. Infinite clarity.

1. Drop leading zeros in any hextet

2. Replace one or more full-zero hextets with :: — once

Now my logs are clean, and configs are readable.

Who else is hooked on IPv6 compression? Trickish sometimes … more practice.

Drop your favorite tricks and moments below!

Let’s make IPv6 the default — one clean address at a time.

[Seyram Kelvin Anku-Etu]

We need IPv6 because IPv4 is almost run out and to meet the growing demands of IoT devices.

IPV6: The Future to advanced and modern networking

[samson Mawisire]

we need IPv6 because due to the growth of the internet usage (devices that needs to be connected) the 32bit IPV4 has not enough addresses to address the need. We have been using the NAT trying to overcome the shortage however a long term solution, the 128 bit IPV6 was needed to take care of that.

[Vimbayi Mangunda]

I can not seem to pass through the Topic Why has IPv6 lasted this long? Is there a bug. Please, can this be fixed as it just gets stuck

[Bernard Bani]

We need it because it is more secure. IPsec is embedded in the header

[Madalitso Cheyo]

IPv6 is the modern replacement for IPv4. We need it because IPv4 addresses are nearly exhausted, and IPv6 provides enough addresses, simpler routing, better security, and scalability for the future of the internet.

[Mamolebo Seboka]

IPv6 is the new version of the internet protocol which identifies devices on a network and route data across the internet.

We need IPv6 because its address size is 128-bit compared to IPv4 which size is 32-bit, address count IPv6 is 340 undecillions while IPv4 is 4.3 billion. IPv6 no NAT needed and security is built-in whereas in IPv4 security is optional.

[HERMAN KAMAU]

With the massive connectivity to the internet in this age, increasing population that needs to stay online with avious IOT Devices, we have come to a point whereby public IPV4 address are running out. Due to this IPV6 was introduced to spearhed the new age of connecting devices due to its large address space and its inbuilt security.
