More information about About Us. Every device connected to the Internet needs to have an identifier. Internet Protocol IP addresses are the numerical addresses used to identify a particular piece of hardware connected cier the Internet.
Both IPv4 and IPv6 addresses come from finite pools of numbers. For IPv4, this pool is bits 2 32 in size and contains 4,, IPv4 addresses. The IPv6 address space is bits 2 in size, chrt ,,,,,, IPv6 addresses. Some IP addresses have been reserved for other uses, such as for use in private networks. This means that the total number of IP addresses available for allocation is less than the total number in the pool. IP addresses can be taken from the IPv4 or the IPv6 pool and are divided into two parts, a network section and a host section.
The cgart section identifies the particular network and the host section identifies the particular node for example, a certain computer on the Local Area Network LAN. The size of the prefix, in bits, is written after the oblique. There is a total of 32 bits chsrt IPv4 address space.
From this, the number of bits left for address space can be cier. This is enough space for host addresses. These host addresses are the IP addresses that are necessary to connect your machine to the Internet.
IPv6 is similar to IPv4, but it is structured so that all LANs have 64 bits of network prefix as opposed to the variable length of network prefix 1 that IPv4 networks have.

All IPv6 networks have space for 18,,, IPv6 addresses. To give some perspective, it is worth noting that there are 4,, IPv4 addresses in total, significantly less than the number of IPv6 addresses.

A bit is a digit in the binary numeral system, the basic unit for storing information.
