IPv4 to IPv6 Converter
Convert between IPv4 and IPv6 address formats including mapped, compatible, and tunnel addresses
How to Use the IPv4 to IPv6 Converter
1. Enter IP Address: Input an IPv4 address (e.g., 192.168.1.1) or IPv6 address (e.g., 2001:db8::1)
2. Select Conversion Type: Choose between IPv4 to IPv6 or IPv6 to IPv4 conversion
3. Click Convert: Press the convert button or hit Enter to perform the conversion
4. View Results: See all possible conversion formats with descriptions
5. Copy Results: Click the copy button to copy any result to your clipboard
IPv4 to IPv6 Conversion Types
IPv4-Mapped IPv6: ::ffff:x.x.x.x format for dual-stack applications
IPv4-Compatible IPv6: ::x.x.x.x format (deprecated but still used)
6to4 Tunnel: 2002:xxxx:xxxx:: automatic tunnel format
Teredo Tunnel: 2001:0000:xxxx:xxxx:: tunneling protocol
ISATAP Tunnel: fe80::xxxx:xxxx:xxxx:xxxx intra-site tunnel
Reverse Conversion: Extract IPv4 from embedded IPv6 addresses
Common Use Cases
• Network Migration: Convert IPv4 addresses to IPv6 for dual-stack deployment
• Tunnel Configuration: Generate 6to4 or Teredo tunnel addresses
• Application Development: Handle IPv4-mapped IPv6 addresses in code
• Network Troubleshooting: Understand embedded IPv4 addresses in IPv6
• Security Analysis: Analyze tunnel addresses and their embedded IPv4
• Documentation: Convert addresses for network documentation
Supported Input Formats
• IPv4 Addresses: 192.168.1.1, 8.8.8.8, 10.0.0.1
• IPv6 Addresses: 2001:db8::1, ::ffff:192.168.1.1, 2002:c0a8:0101::
• Compressed IPv6: ::1, 2001:db8::, fe80::1
• Mixed Format: IPv4-mapped and compatible IPv6 addresses
Technical Notes
• IPv4-Mapped IPv6: Most common format for dual-stack applications
• 6to4 Tunnels: Use the first 32 bits of the IPv4 address as the tunnel prefix
• Teredo: Provides IPv6 connectivity through NAT devices
• ISATAP: Used for IPv6 connectivity within IPv4 networks
• Reverse Conversion: Only works with embedded IPv4 addresses
