Expanded: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
Scope: Global Unicast
How It Works
- Parses 128-bit hextet syntax and normalizes representation per RFC 5952.
Formula & Technical Standard
128 bits divided into eight 16-bit blocks in hexadecimal.
Practical Example
Loopback
Input: ::1
Output: 0000:0000:0000:0000:0000:0000:0000:0001 (Loopback)
Canonical expansion.
