IP Find IPv6 Subnet/Network and its host address ranges

What is an IPv6 IP address its network and host address ranges?

IPv6 addresses are each 128 bits long. Because each digit in an IPv6 address can have 16 different values (from 0 to 15), each digit represents the overall value of 4 bits (one nibble), with 32 digits total. As with IPv4, CIDR notation describes ranges in terms of a common prefix of bits. For example 2001:db8::/32 means that the range described has the first 32 bits set to the binary digits 00100000000000010000110110111000. Also like IPv4, MediaWiki implements IPv6 rangeblocks using CIDR notation.
Following are the ranges of IPv6 subnet/network address and their host addresses.

How IPv6 host addresses we calculated?

As we explained above IPv6 IP version is 128 bit long. Our system get IPv6 IP address as input in URL parameter value with its CIDR & get its all host address ranges from our largest database get back its start range and last range with its relevant CIDR at the end final IPv6 which converts into IPv4 IP address by our tool IPv6 to IPv4 converter.
