About this Network
This calculator provides subnet details for the IPv6 network 2003:: with prefix length /64. This network is part of the Global Unicast address space and is typically used for Global unicast example 1.
Prefix Length Details
A /64 prefix length means: - Network portion: First 64 bits - Host portion: Remaining 64 bits - Total possible addresses: 2^64
Common Uses
A /64 prefix is the standard subnet size, allowing for stateless address autoconfiguration (SLAAC).
Global Unicast Address Space
Global Unicast addresses are the IPv6 equivalent of public IPv4 addresses. They are globally routable and reachable on the IPv6 Internet. The address space begins with binary 001 (2000::/3).
Technical Specifications
- Address Type: Global Unicast
- Primary Use Case: Global unicast example 1
- Prefix Length: /64
- Interface ID Bits: 64
Best Practices for /64 Networks
Standard Subnet
Ideal for end-user networks. Enables stateless address autoconfiguration (SLAAC).
