IPv4 to IPv6 Converter - Convert Between IP Address Formats

IPv4 to IPv6 Converter

Convert between IPv4 and IPv6 address formats for dual-stack network configurations.

What is IPv4 to IPv6 Conversion?

As the internet transitions from IPv4 to IPv6, dual-stack networks need to represent IPv4 addresses in IPv6 format. This converter generates different IPv6 representations of IPv4 addresses for compatibility and transition mechanisms.

Conversion Methods:

  • IPv4-Mapped IPv6: Format ::ffff:x.x.x.x - Used for dual-stack systems
  • 6to4 Address: Format 2002::/16 - Automatic tunneling mechanism
  • IPv6 to IPv4: Extract IPv4 from IPv4-mapped IPv6 addresses

Why Convert IP Address Formats?

  • Dual-Stack Networks: Support both IPv4 and IPv6 simultaneously
  • Network Migration: Transition from IPv4 to IPv6 infrastructure
  • Application Compatibility: Enable IPv6-only apps to communicate with IPv4 hosts
  • Firewall Rules: Configure rules for both IP versions
  • Network Documentation: Document IP addresses in both formats

How to Use the IP Converter

Step 1: Enter an IPv4 address (e.g., 192.0.2.1) or IPv6 address (e.g., ::ffff:192.0.2.1)
Step 2: Select conversion direction (IPv4→IPv6 or IPv6→IPv4)
Step 3: Click "Convert" to see all format variations
Step 4: Use "Copy Results" to save the converted addresses

Example Conversion:

Input IPv4: 192.0.2.1

Results:
Original Address: 192.0.2.1
IPv4-Mapped IPv6: ::ffff:192.0.2.1
IPv6 Compressed: ::ffff:c000:201
6to4 Address: 2002:c000:201::

---

Input IPv6: ::ffff:192.0.2.1

Results:
Original Address: ::ffff:192.0.2.1
IPv4 Address: 192.0.2.1

Understanding IPv6 Addresses:

  • Length: 128 bits (vs 32 bits for IPv4)
  • Format: Eight groups of four hexadecimal digits
  • Compression: Consecutive zeros can be replaced with ::
  • Example: 2001:0db8:0000:0000:0000:ff00:0042:8329
  • Compressed: 2001:db8::ff00:42:8329
