7 Best Free IPv4 to IPv6 Converter Online

Here is a list of the best free IPv4 to IPv6 converter online. IPv4 and IPv6 are the two versions of Internet Protocol addresses. IPv4 was launched in 1983 and is still used today. The IPv4 addresses are 32-bit long and broken up into four 8-bit octets. For example, 192.2..0.12, 192,168,200,55, etc. But with the exponential growth of internet and IoT devices IPv4 fell short. Thus came the next version, IPv6. IPv6 addresses are 128-bit long (4 times of IPv4) and use both numbers and letters. It is represented by eight groups of four hexadecimal digits, separated by a colon. For example, 0000:0000:0000:0000:0000:ffff:bc00:4800.
