An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [1] [2] IP addresses serve two main functions: network interface identification, and location addressing.
For example, the quad-dotted IP address in the illustration (172.16.254.1) represents the 32-bit decimal number 2886794753, which in hexadecimal format is 0xAC10FE01. CIDR notation combines the address with its routing prefix in a compact format, in which the address is followed by a slash character (/) and the count of leading consecutive 1 ...
Address record Returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but it is also used for DNSBLs , storing subnet masks in RFC 1101, etc. AAAA
IPv6 multicast: [41] The low 32 bits an Ethernet address for IPv6 multicast traffic are the low 32 bits of the multicast IPv6 address used. [40]: §2.3.1 For example, IPv6 multicast traffic using the address ff02::d uses the MAC address 33-33-00-00-00-0D, and traffic to ff05::1:3 goes to the MAC address 33-33-00-01-00-03. 01-0C-CD IEC

In computing, a virtual address space (VAS) or address space is the set of ranges of virtual addresses that an operating system makes available to a process. [1] The range of virtual addresses usually starts at a low address and can extend to the highest address allowed by the computer's instruction set architecture and supported by the operating system's pointer size implementation, which can ...
The original list of IPv4 address blocks was published in September 1981. [3] In previous versions of the document, [18] [19] network numbers were 8-bit numbers rather than the 32-bit numbers used in IPv4. At that time, three networks were added that were not listed earlier: 42.rrr.rrr.rrr, 43.rrr.rrr.rrr, and 44.rrr.rrr.rrr.
While IPv4 uses 32 bits for addressing, yielding c. 4.3 billion (4.3 × 10 9) addresses, IPv6 uses 128-bit addresses providing c. 3.4 × 10 38 addresses. Although adoption of IPv6 has been slow, as of January 2023 [update] , most countries in the world show significant adoption of IPv6, [ 10 ] with over 41% of Google's traffic being carried ...
