IPv4 to IPv6 Converter
Convert an IPv4 address to its IPv4-mapped IPv6 forms, full notation and 6to4 prefix.
| IPv4-mapped (dotted) | ::ffff:192.168.1.1 | |
| IPv4-mapped (hex) | ::ffff:c0a8:0101 | |
| Full expanded form | 0000:0000:0000:0000:0000:ffff:c0a8:0101 | |
| 6to4 prefix | 2002:c0a8:0101:: |
Enter an IPv4 address to see its IPv4-mapped IPv6 representations in several notations.
How to use
- Type an IPv4 address such as 192.168.1.1.
- Read the ::ffff: mapped forms.
- Copy the notation you need.
Frequently asked questions
- What is an IPv4-mapped IPv6 address?
- It embeds an IPv4 address inside IPv6 using the ::ffff:0:0/96 prefix, letting IPv6 sockets represent IPv4 endpoints.
- What is the 6to4 prefix?
- 6to4 uses the 2002::/16 prefix with the IPv4 address in the next 32 bits to route IPv6 traffic over IPv4 networks.
