What is IPv6 and why do we need it?

[Helder Piedade]

IPv6, with its 128‑bit address space, provides more than enough unique addresses, ensuring an effectively inexhaustible supply of IP addresses for global networking requirements into the foreseeable future.

IPv6 is the latest networking layer protocol that provides unique IP addresses for internet-enabled devices, replacing the exhausted 32-bit IPv4 system with a 128-bit structure. It is necessary because the massive expansion of IoT ,smart devices has depleted the IPv4 addresses available.

IPv4 uses a 32-bit address space, which only provides about 4.3 billion addresses. With the explosion of smartphones, IoT devices, and always-on satellite connections (like Starlink), the world has officially run out of new IPv4 addresses.

With advancements in technology, such as IoT, big data, and AI, IPv6 is required. It provides built-in security features, a simplified header that reduces delays in application performance, and a larger IP address space, which improves network planning

[DICKSON KASANO]

IPv6 is the internet’s updated addressing system, providing a virtually infinite supply of unique IDs to replace the exhausted IPv4 protocol.
It is necessary because the original 4.3 billion address limit cannot support the billions of smartphones and smart devices now online.
The upgrade streamlines connectivity by allowing direct device communication, improving routing efficiency, and providing stronger built-in security.
