IPv4 to IPv6 Address Converter
Convert any 32-bit IPv4 address into its corresponding 128-bit IPv6 representations. Generate IPv4-Mapped IPv6 notation, 6to4 transitional tunneling addresses, expanded formats, and compressed zero-shortened notations.
How to Use IPv4 to IPv6 Converter & Mapper
Enter IPv4 Address
Input any valid IPv4 address (e.g., 192.0.2.1).
View Converted Formats
Instantly view IPv4-mapped, 6to4 prefix, Decimal, and Hexadecimal representations.
Copy Desired Format
Copy compressed (RFC 5952) or fully expanded 8-group IPv6 strings.
About IPv4 to IPv6 Converter & Mapper
IPv4 provides approximately 4.3 billion unique addresses (32-bit), which have been exhausted globally. IPv6 utilizes 128-bit addressing, providing 3.4 × 10³⁸ unique addresses. During the multi-decade transition, IPv4-mapped IPv6 addresses allow dual-stack operating systems to handle both protocols using standard IPv6 sockets.
Key Features
- IPv4-Mapped IPv6 format: ::ffff:192.0.2.1 and ::ffff:c000:0201
- 6to4 transitional address: 2002:c000:0201::/48
- Full 8-group expanded format with leading zeros
- RFC 5952 compliant compressed representation (shortening consecutive zeros with ::)
- Integer, Hexadecimal, and Binary IP translations
