ARIN manages the distribution of Internet number resources, including IPv4 and IPv6 address space and AS numbers. ARIN opened for business on December 22, 1997 [1] after incorporating on April 18, 1997. [2] ARIN is a nonprofit corporation with headquarters in Chantilly, Virginia, United States. [3] [4]
A regional Internet registry (RIR) is an organization that manages the allocation and registration of Internet number resources within a region of the world. Internet number resources include IP addresses and autonomous system (AS) numbers.
Miredo [1] is a Teredo tunneling client designed to allow full IPv6 connectivity to computer systems which are on the IPv4-based Internet but which have no direct native connection to an IPv6 network. Miredo is included in many Linux [2] [3] and BSD [4] [5] distributions and is also available for recent versions of Mac OS X. [6] (Discontinued)
IPv6 addresses are assigned to organizations in much larger blocks as compared to IPv4 address assignments—the recommended allocation is a / 48 block which contains 2 80 addresses, being 2 48 or about 2.8 × 10 14 times larger than the entire IPv4 address space of 2 32 addresses and about 7.2 × 10 16 times larger than the / 8 blocks of IPv4 ...
It is a successor to the WHOIS protocol, used to look up relevant registration data from such Internet resources as domain names, IP addresses, and autonomous system numbers. While WHOIS essentially retrieves free text, RDAP delivers data in a standard, machine-readable JSON format. [1]
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol–related symbols and Internet numbers.
The allocation of IP addresses is important for several reasons. Public addresses need to be unique; if duplicate internet addresses existed on a network, network traffic could be delivered to the wrong host. The RIRs make sure that public addresses are given to one organisation. The RIPE NCC does this for its own service region.
A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [ 2 ] (routable only within the scope of private networks, but not the global IPv6 Internet).
