What is an IP address?

IP address is the abbreviation of Internet Protocol Address, which is a numerical address that uniquely identifies every device on the Internet (such as computers, mobile phones, network printers, etc.). IP addresses are used to identify and locate devices on the Internet, allowing them to communicate and exchange data. IP addresses generally consist of 32-bit (IPv4) or 128-bit (IPv6) binary numbers, usually expressed in decimal form.

Range of IPv4 addresses

IPv4 addresses range from to IPv4 addresses are represented by 32-bit binary numbers, usually in dotted decimal notation. The first network address and the last broadcast address are reserved separately, so the available IPv4 address range is to

Range of IPv6 addresses

The range of IPv6 addresses is 2^128, which is 340,282,366,920,938,463,463,374,607,431,768,211,456. The IPv6 address length is 128 bits, which is much larger than the IPv4 address length (32 bits), so the range of IPv6 addresses is also wider. IPv6 addresses were designed to solve the problem of insufficient IPv4 addresses to support more devices and users on the Internet.

What can the IPv4/IPv6 address translation calculator do?

IPv4/IPv6 Address Calculator is an IP address calculation tool used to calculate the compressed address, extended address, binary address, subnet mask, start address, end address and other values of a IP address. At the same time, the tool also supports reverse DNS queries for the IP address.
