Internet architecture Internet architecture The 6bone is an IPv6 Testbed that is an outgrowth of the IETF IPng project that created the IPv6 protocols intended to eventually replace the current Internet network layer protocols known as IPv4. The 6bone was started outside the official IETF process at the March 1996 IETF meetings, and became a world wide informal collaborative project, with eventual oversight from the "NGtrans" (IPv6 Transition) Working Group of the IETF. ...more on Wikipedia about "6bone"
6to4 (sometimes written 6 to 4) is a system that allows IPv6 packets to be transmitted over an IPv4 network (generally the IPv4 internet) without the need to configure explicit tunnels. Routing conventions are also in place that allow 6to4 hosts to communicate with hosts on the IPv6 internet. It is typically used when an end site or end user wants to connect to the IPv6 internet using their existing IPv4 connection. ...more on Wikipedia about "6to4"
An address pool is a set of IP addresses assigned by IANA or an organisation tied to it. ...more on Wikipedia about "Address pool"
Anycast is a network addressing and routing scheme whereby data is routed to the "nearest" or "best" destination as viewed by the routing topology. ...more on Wikipedia about "Anycast"
In the Internet, an autonomous system (AS) is a collection of IP networks and routers, under the control of one or more entities, that presents a common routing policy to the Internet. See RFC 1930 for additional detail on this updated definition. ...more on Wikipedia about "Autonomous system (Internet)"
In computer networking, a broadcast address is an IP address that allows information to be sent to all machines on a given subnet rather than a specific machine. The exact notation can vary by operating system, but the standard is laid out in RFC 919. ...more on Wikipedia about "Broadcast address"
Classful networking is the name given to the first round of changes to the structure of the IP address in IPv4. ...more on Wikipedia about "Classful network"
Classless Inter-Domain Routing (CIDR, pronounced "cider"), introduced starting in 1993, is the latest refinement to the way IP addresses are interpreted. It replaced the previous generation of IP address syntax, classful networks. It allowed increased flexibility when dividing ranges of IP addresses into separate networks. It thereby promoted: ...more on Wikipedia about "Classless Inter-Domain Routing"
In telecommunications, connection-oriented describes a means of transmitting data in which the devices at the end points use a preliminary protocol to establish an end-to-end connection before any data is sent. Connection-oriented protocol service is sometimes called a "reliable" network service, because it guarantees that data will arrive in the proper sequence. Transmission Control Protocol (TCP) is a connection-oriented protocol. ...more on Wikipedia about "Connection-oriented protocol"
In telecommunications, connectionless describes communication between two network end points in which a message can be sent from one end point to another without prior arrangement. The device at one end of the communication transmits data to the other, without first ensuring that the recipient is available and ready to receive the data. The device sending a message simply sends it addressed to the intended recipient. If there are problems with the transmission, it may be necessary to resend the data several times. The Internet Protocol (IP) and User Datagram Protocol (UDP) are connectionless protocols. ...more on Wikipedia about "Connectionless protocol"
The terms dark internet or dark address refer to any or all of the unreachable network hosts on the Internet. ...more on Wikipedia about "Dark internet"
A default route is the network route used by a router or a server when no other known route works for a given IP packet's destination address. All the packets for destinations not known by the server or routers routing table are send to the default route. A router determines which route is valid to reach an IP address by finding the " most specific match". That is, the network with the longest subnet mask that matches the IP address, wins. ...more on Wikipedia about "Default route"
DiffServ or differentiated services is a method of trying to guarantee quality of service on large networks such as the Internet. ...more on Wikipedia about "Differentiated services"
The end-to-end principle is one of the central design principles of the Internet Protocol (IP) that is the basis of the Internet. It states that, whenever possible, communications protocol operations should be defined to occur at the end-points of a communications system. ...more on Wikipedia about "End-to-end principle"

In computer networking, IntServ or integrated services is an architecture, which specifies the elements to guarantee quality of service (QoS) on networks. IntServ can for example be used to allow video and sound to reach the receiver without interruption. ...more on Wikipedia about "Integrated services"
The Internet backbone was the central network that linked all the parts of the Internet together. The term is now used as a loose term to describe the "core" of the current Internet. ...more on Wikipedia about "Internet backbone"
The Internet Protocol (IP) is a data-oriented protocol used by source and destination hosts for communicating data across a packet-switched internetwork. ...more on Wikipedia about "Internet Protocol"
An Internet transit is an arrangement when one Internet service provider carries packets for another provider to or from the wider Internet. In the very early Internet, the assumption was made that all networks would provide transit for one another; however, in the commercial Internet, this is commercially unsustainable. ...more on Wikipedia about "Internet transit"
An IP address (Internet Protocol address) is a unique number that devices use in order to identify and communicate with each other on a network utilizing the Internet Protocol standard. Any participating device — including routers, computers, time-servers, internet FAX machines, and some telephones — must have its own unique address. This allows information passed onwards on behalf of the sender to indicate where to send it next, and for the receiver of the information to know that it is the intended destination. ...more on Wikipedia about "IP address"
IP address allocation is the process of distributing IP addresses to organizations world-wide. It is managed by IANA and several Regional Internet Registries (RIRs). ...more on Wikipedia about "IP address allocation"
The Internet Protocol allows IP fragmentation so that datagrams can be fragmented into pieces small enough to pass over a link with a smaller MTU than the original datagram size. ...more on Wikipedia about "IP fragmentation"
IP over Avian Carriers or RFC 1149 is a humorous Request for Comments document issued by the Internet Engineering Task Force. It describes how Internet Protocol traffic may be carried by homing pigeons. It was written by D. Waitzman and released on April Fool's Day 1990, one of the April 1st RFCs. ...more on Wikipedia about "IP over Avian Carriers"
IP transit is a form by which wholesale Internet bandwidth is sold to Internet Service Providers (ISPs) and content providers. Pricing is typically offered on a per megabit per second per month basis (Mbps/Month) and requires the purchaser to commit to a minimum volume of bandwidth. Pricing for the bandwidth can be reduced significantly by purchasing larger volumes or extending the contract term. ...more on Wikipedia about "IP transit"
IPv4 is version 4 of the Internet Protocol (IP). It was the first version of the Internet Protocol to be widely deployed, and forms the basis for most of the current Internet ( as of 2006). ...more on Wikipedia about "IPv4"
As the number of Internet-connected devices increases, the address space of the current IPv4 version of the TCP/IP protocol suite is rapidly being consumed by allocations for new devices. This creates an IPv4 address shortage, and could conceivably result in IPv4 address exhaustion. ...more on Wikipedia about "IPv4 address exhaustion" Simply http://www.shortopedia.com!
