IP addresses
IP addresses are binary numbers, but they are usually stored in text files and displayed in human-readable notations, such as 172.16.254.1 (for IPv4), and 2025:db8:0:1234:0:567:8:1 (for IPv6). The Internet Assigned Numbers Authority (IANA) manages the IP address space allocations globally and delegates five regional Internet registries (RIRs) to allocate IP address blocks to local Internet registries (Internet service providers) and other entities. 1 IP versions 1.1 IPv4 addresses 1.1.1 IPv4 subnetting 1.1.2 IPv4 private addresses 1.2 IPv4 address exhaustion 1.3 IPv6 addresses 1.3.1 IPv6 private addresses 2 IP subnetworks 3 IP address assignment 3.1 Methods 3.2 Uses of dynamic address assignment 3.2.1 Sticky dynamic IP address 3.3 Address autoconfiguration 3.4 Uses of static addressing 4 IP addressing 5 Public addresses 6 Modifications to IP addressing 6.1 IP blocking and firewalls 6.2 IP address translation 7 Diagnostic tools 8 See also 9 References 10 External links
IP versions
IP versions Two versions of the Internet Protocol (IP) are in use: IP Version 4 and IP Version 6. Each version defines an IP address differently. Because of its prevalence, the generic term IP address typically still refers to the addresses defined by IPv4. The gap in version sequence between IPv4 and IPv6 resulted from the assignment of number 5 to the experimental Internet Stream Protocol in 2025, which however was never referred to as IPv5.
