  • About IPv6 to IPv4 Converter

    IPv6 to IPv4 conversion calculator instantly maps a given IPv6 address to its equivalent IPv4 address. Please enter the valid IPv6 format, and the tool instantly converts the given IPv6 to its IPv4 equivalent.

    The tool provides IPv6-mapped IPv4 addresses or 6to4 notation. It benefits when using the same IPv6 address in its IPv4 variant. If you want to perform the reverse conversion, you can do this with IPv4 to IPv6 address converter.

    What are IPv4 and IPv6?

    Before diving deeper into IPv4 and IPv6 addresses, one must have an idea of what is an IP address?

    An IP address or Internet Protocol address is a unique number string assigned to each device connected to the computer network. An IP address, also known as an Internet address, is categorized into two main versions: IPv4 and IPv6.

    1: IPv4 address

    IPv4 address is the most commonly recognized IP address version and carries most internet traffic. It uses a 32-bit address scheme and contains more than 4 billion IP addresses (4,294,967,296 in exact amount).

    2: IPv6 address

    Although the IPv4 address carries most Internet traffic, however, due to the unconstructed distribution of IPv4 addresses, the world realized the upcoming shortage of IPv4 addresses. Therefore, to overcome the future scarcity, IPv6 was introduced.

    IPv6 address is the latest and most up to dated IP version. It uses a 128-bit address scheme and contains more than 340 undecillion IP addresses (340,282,366,920,938,463,463,374,607,431,768,211,456 in exact amount). However, the actual number is slightly less, as several ranges are for a particular use or excluded to use.

    An example of an uncompressed form of IPv6 is: fe80:cd00:0000:0cde:1257:0000:211e:729c

    However, you can compress the IPv6 as per your need.

    How to map a valid IPv6 address into an IPv4 address or 6to4 notation?

    To map a valid Internet Protocol Version 6 address into Internet Protocol Version 4 address or 6to4 notation, perform the following steps.

    1. Open the IPv6 to IPv4 Converter.
    2. Enter a valid IPv6 address. Suppose you enter an IPv6 address 0:0:0:0:0:ffff:0370:7334.
    3. Click on the "Convert IPv6 to IPv4" button.
    4. The tool processes your request and provides you with a converted IPv4 address.
    5. In the case of the above entered IPv6 address, the tool provides you with the following result in IPv4 format 3.112.115.52.

    To break down a single network into smaller networks, use an IP subnet calculator for subnetting.

    Is there is a one-one correspondence between IPv4 and IPv6 addresses?

    The IPv4 address is 32-bit long, and the IPv6 address is 128-bit long. Thus, IPv6 addresses are 1028 times larger than IPv4 addresses in numbers. Therefore, you cannot convert all the IPv6 addresses to IPv4 addresses. A particular range of IPv6 addresses represents the IPv4 addresses space. You can only convert those valid IPv4 represented IPv6 addresses.
