What is IPv6?
Internet Protocol version 6 (IPv6) is the latest IP revision, developed as a successor to the now depleted IPv4.
IPv6 differs from IPv4 in many ways, including address size, format, notation, and possible combinations:
|Address Size:||32-bit number||128-bit number|
|Address Format:||Dotted Decimal Notation
|Number of Addresses:||2^32

Why Adopt IPv6?
Now that ARIN has reached IPv4 exhaustion, we strongly encourage you to adopt IPv6 on your networks. Not only does IPv6 offer a variety of improvements over IPv4, the Internet simply cannot continue to grow without it!

IPv6 @ ARIN
How do I get started?
- Make sure your equipment, software, and staff are ready for IPv6. Visit the Get IPv6 Wiki for tips.
- Request an IPv6 assignment, or if you plan to distribute IPv6 addresses to your customers, an allocation.
- Implement IPv6 on your network's hardware and applications, using the Get IPv6 Wiki for implementation advice and shared experiences from other organizations who have implemented IPv6 already.
