Who is ipv6 lookup

You can read case studies from organizations that have already adopted IPv6 including ISPs, hosting providers, enterprise businesses, universities, and governments. IPv6 differs from IPv4 in many ways, including address size, format, notation, and possible combinations. An IPv6 address consists of bits as opposed to the bit size of IPv4 addresses and is expressed in hexadecimal notation.

The IPv6 anatomy graphic below represents just one possible configuration of an IPv6 address, although there are many different possibilities. As with IPv4, in IPv6 there is no way to definitively calculate the netmask and gateway using only a given address.

Both are established when a person sets up a network, and you would need to contact your network administrator to determine what they are.

However, when given an address and a prefix, one can compute the starting and ending addresses of a subnet, just like in IPv4. Note that the length of a given IPv6 network prefix cannot be shorter than the registered IPv6 allocation or assignment. There is no strong convention as to where to number the gateway; although choosing the smallest number in the network is common. What is IPv6?
