	IP address - Wikipedia, the free encyclopedia
		An IP address can also be thought of as the equivalent of a street address or a phone number (compare: VoIP) for a computer or other network device on the internet.
		An IP address can appear to be shared by multiple client devices either because they are part of a shared hosting web server environment or because a proxy server (e.g.
		IP addresses may either be assigned permanently (for example, to a server which is always found at the same address) or temporarily from a pool of available addresses.

	. IP address (Site not responding. Last check: 2007-10-30)
		IP addresses are conceptually similar to phone numbers, except they are used in LANs (Local Area Network), WANs (Wide Area Network), or the Internet.
		IP addresses are usually given out through a server service called DHCP or the Dynamic Host Configuration Protocol.
		While a number of measures have been taken to conserve the limited existing IPv4 address space (such as the use of NAT and Private Addressing), the number of 32-bit IP addresses is not sufficient to accommodate the long-term growth of the Internet.

	IP address - All About All (Site not responding. Last check: 2007-10-30)
		An IP address (Internet Protocol address) is a unique number, similar in concept to a telephone number, used by network devices (routers, computers, time-servers, FAX machines, some telephones) attached to a network to refer to each other when sending information through a LAN (Local Area Network), WAN (Wide Area Network) or the Internet for example.
		The IP addresses of users browsing the world wide web are used to enable communications with the server of the web site.
		IP addresses are usually given out through a service called DHCP or the Dynamic Host Configuration Protocol.

	RFC 1918 (rfc1918) - Address Allocation for Private Internets
		Addresses within this private address space will only be unique within the enterprise, or the set of enterprises which choose to cooperate over this space so they may communicate with each other in their own private internet.
		Once one commits to using a private address, one is committing to renumber part or all of an enterprise, should one decide to provide IP connectivity between that part (or all of the enterprise) and the Internet.
		To minimize the risk it is strongly recommended that an organization using private IP addresses choose randomly from the reserved pool of private addresses, when allocating sub-blocks for its internal allocation.

	IP Address Allocation Policy - Arogo.Net
		Therefore, IP address space is allocated to ISP's using a slow-start model.
		IP address allocations are valid as long as the utilization and other relevant criteria continue to be met, and the yearly fee is submitted.
		Any IP addresses that cannot be verified are viewed as a "convenience" allocation by ARIN and may have a negative impact on our further IP allocations from ARIN.

	RFC1518 An Architecture for IP Address Allocation with CIDR - Digipedia
		IP partitions the routing problem into three parts: - routing exchanges between end systems and routers (ARP), - routing exchanges between routers in the same routing domain (interior routing), and, - routing among routing domains (exterior routing).
		IP Addresses and Routing For the purposes of this paper, an IP prefix is an IP address and some indication of the leftmost contiguous significant bits within this address.
		When determining an administrative policy for IP address assignment, it is important to understand the technical consequences.

	Why IPv6 will not loosen IP address allocation
		This is leading to a worldwide crunch in the availability of addresses, and rationing is in effect, specially in Asia, which came late to the Internet party and has a short allocation (Stanford University has more IPv4 addresses allocated to it than the whole of China).
		Many people make do today with Network Address Translation (NAT), where a box (like a DSL router) allows several machines to share a single global IP address, but this is not an ideal solution, and one that only postpones the inevitable (but not imminent) reckoning.
		One misconception, however, is that that the slow pace of the migration is somehow related to the fact you get your IP addresses from your ISP, and don't "own" them or have the option to port them the way you now can with your fixed or mobile phone numbers.

	RFC 1518 (rfc1518) - An Architecture for IP Address Allocation with CIDR
		The first is the set of administrative requirements for obtaining and allocating IP addresses; the second is the technical aspect of such assignments, having largely to do with routing, both within a routing domain (intra-domain routing) and between routing domains (inter-domain routing).
		Having IP addresses derived from a backbone is inconsistent with the nature of the relationship.
		Note that the relationship between routing and IP addressing described in other sections of this paper is concerned with problems in scaling caused by large, essentially public transit routing domains which interconnect a large number of routing domains.

		Hosts within enterprises that use IP can be partitioned into three categories: Category 1: hosts that do not require access to hosts in other enterprises or the Internet at large; hosts within this category may use IP addresses that are unambiguous within an enterprise, but may be ambiguous between enterprises.
		Rekhter, et al Best Current Practice [Page 5] RFC 1918 Address Allocation for Private Internets February 1996 A major drawback to the use of private address space is that it may actually reduce an enterprise's flexibility to access the Internet.
		If such companies prior to the merge maintained their uncoordinated internets using private address space, then if after the merge these private internets would be combined into a single private internet, some addresses within the combined private internet may not be unique.

		According to the AUNIC database, address space was allocated to you between 1993 and 1997, either by AUNIC or by AARNet (the Australian Academic and Research Network) prior to the establishment of AUNIC.
		On 1 July 2001, IP address records will be removed from the AUNIC database, and replaced with a single referral record pertaining to the entire 203.0/10 address block.
		In February 1997 AUNIC's address allocation operation ceased, and applicants for address space were redirected to their upstream ISP or to the Regional Internet Registry, the Asia Pacific Network Information Centre (APNIC).

	IP Address Allocation by ISPs (Site not responding. Last check: 2007-10-30)
		Blocks of IPs are allocated by IANA (InterNet Assigned Numbers Association), with various blocks being allocated to various regional providers, and it being up to the regional provider as to how the blocks are allocated.
		The bulk of the IPs are allocated for USA; within the USA, IANA will get involved in allocating blocks of IPs, but a /24 is the smallest they will go and they don't even like to do that.
		This is often referred to (somewhat strangely, as the peers obviously still have IP addresses) as "unnumbered mode" or "effectively unnumbered." In other words, there's really no mask on the link.

	IP allocation policy in Israel (Site not responding. Last check: 2007-10-30)
		If all address space has been reserved (as stated in #1) and there is a request for more IP addresses, then ISOC-IL will de-reserve address space in order to allocate it to the new ISP.
		Organizations who receive portable IP addresses due to being multihomed, and who cease to be multihomed, must return the portable IP addresses to ISOC-IL and renumber their systems to use IP addresses as assigned by their ISP.
		The one exception is an organization that has received at least a /22 or larger allocation of IP address space, in which case the block of addresses will be marked as private and portable.
