IPv6 Notation Converter

Convert between compressed and expanded IPv6 notation formats

What is IPv6 Notation Conversion?

IPv6 notation conversion transforms IPv6 addresses between compressed and expanded formats. Compressed notation uses :: to represent consecutive zero groups (e.g., 2001:db8::1), while expanded notation shows all 8 groups with leading zeros (e.g., 2001:0db8:0000:0000:0000:0000:0000:0001). This tool automatically detects the input format and converts to both representations with detailed analysis.

Supported Formats:

Compressed: 2001:db8::1, fe80::1, ::1
Expanded: 2001:0db8:0000:0000:0000:0000:0000:0001
Mixed: 2001:db8:0:0:0:0:0:1

How Does IPv6 Notation Conversion Work?

The conversion process handles both compression and expansion of IPv6 addresses:

  1. Parse input: Detect if address is compressed, expanded, or mixed format
  2. Expand to full: Replace :: with appropriate zero groups, pad with leading zeros
  3. Compress optimally: Find longest sequence of zero groups and replace with ::
  4. Validate format: Ensure proper IPv6 structure and group count
  5. Analyze address: Determine address type and provide detailed breakdown

This tool handles all IPv6 notation formats and provides comprehensive analysis!
