Rule 3: When zeros (0s) are present in discontinuous pattern in IPv6 address notation, then at only one junction, the zeros (0s) are replaced with. This rule is also known as leading zero compression. However, you cannot apply this rule to trailing zeros (0s). Removing leading zeros (0s) does not have any effect on the value. If the field contains all zeros (0s), you have to leave one zero (0) remaining. But each block in which you do this, have at least one number remaining. Rule 2: Leading zeros (0s) in the 16 bits field can be removed. This rule is also known as zero compression. Rule 1: When there are continuous zeros (0s) in the IPv6 address notation, they are replaced with . Ive been reading about the differences between MAC and IP addresses, and why we need both of them. Therefore, several rules are developed to compress and shorten the IPv6 address for convenience of the user. It's a pain in typing all those hexadecimal characters in the IPv6 address. Consider a situation where you have to ping the expanded IPv6 address to check the network connectivity. But IPv6 addresses are lengthy and challenging to use. You can only convert those valid IPv4-represented IPv6 addresses.With time, people are shifting from IPv4 to IPv6 addresses and also perform IPv4 to IPv6 conversion. A particular range of IPv6 addresses represents the IPv4 addresses space. Therefore, you cannot convert all the IPv6 addresses to IPv4 addresses. Thus, IPv6 addresses are 1028 times larger than IPv4 addresses in numbers. The IPv4 address is 32-bit long, and the IPv6 address is 128-bit long. Is there a one-one correspondence between IPv4 and IPv6 addresses? However, you can compress IPv6 as per your need. However, the actual number is slightly less, as several ranges are for a particular use or excluded to use.Īn example of an expanded IPv6 is: fe80:cd00:0000:0cde:1257:0000:211e:729c IPv6 address is the latest and most up to dated IP version. Therefore, to overcome future scarcity, IPv6 was introduced. 2: IPv6 addressĪlthough 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. It uses a 32-bit address scheme and contains more than 4 billion IP addresses (4,294,967,296 in exact amount). IPv4 is the most commonly recognized IP address version and carries most internet traffic. An IP address, or Internet address, is categorized into two main versions: IPv4 and IPv6. What are IPv4 and IPv6?īefore diving deeper into IPv4 and IPv6 addresses, one must have an idea of what is an IP address.Īn IP address or Internet Protocol address is a unique number string assigned to each device connected to the computer network. To break down a single network into smaller networks, use an IP subnet calculator for subnetting. In the case of the above-entered IPv6 address, the tool provides you with the following result in IPv4 format 3.112.115.52.The IPv6 to IPv4 calculator processes your request and provides you with a converted IPv4 address.Click on the "Convert IPv6 to IPv4" button.To map a valid Internet Protocol Version 6 address into Internet Protocol Version 4 address, IPv6 to IPv4 conversion, or 6to4 notation, perform the following steps. How can a valid IPv6 address be mapped into an IPv4 address or 6to4 notation? If you want to perform the reverse conversion, you can do this with IPv4 to IPv6 converter. It benefits when using the same IPv6 address in its IPv4 variant. The IPv6 to IPv4 converter provides IPv6-mapped IPv4 addresses or 6to4 notation. IPv6 to IPv4 Converter - Convert IPv6 to IPv4
