2. IP address FREDDY P.V Email :F4FREDDY@GMAIL.COM Facebook :F4FREDDY@GMAIL.COM 3. IP Short for Internet Protocol. IP specifies the format of packets, also called datagrams,and the addressing scheme. Most networks combine IP with a higher-level protocolcalled Transmission Control Protocol (TCP), whichestablishes a virtual connection between a destination anda source. The current version of IP is IPv4. A new version, called IPv6or IPng, is under development. 4. IP address IP address is short for Internet Protocol (IP)address. An IP address is an identifier for a computer ordevice on a TCP/IP network. Networks using the TCP/IP protocol routemessages based on the IP address of thedestination. 5.

An IP address is a unique global address for anetwork interface The format of an IP address is a 32-bit numericaddress written as four numbers separated byperiods. Each number can be zero to 255. Example, 1.160.10.240 could be an IP address. 10. IP address Classes5 Classes of IP address A B C D and EClass A reserved for governmentsClass B reserved for medium companiesClass C reserved for small companiesClass D are reserved for multicastingClass E are reserved for future use 11. IP structure Class A begins 1 to 126 Class B begins 128 to 191 Class C begins 192 to 223 12. How does your computer get its IPaddress? An IP address can be either dynamic or static. A static address is one that you configure yourself byediting your computers network settings. Dynamic addresses are the most common. Theyreassigned by the Dynamic Host ConfigurationProtocol (DHCP), a service running on the network. DHCP typically runs on network hardware such asrouters or dedicated DHCP servers. 13. Internet Protocol version 4 (IPv4) It is the fourth revision in the development of the InternetProtocol (IP) and the first version of the protocol to be widelydeployed. Together with IPv6, it is at the core of standards-basedinternetworking methods of the Internet. As of 2012 IPv4 is still the most widely deployed InternetLayer protocol 14. IPv4 is a connectionless protocol for use on packet-switched LinkLayer networks (e.g., Ethernet). It operates on a best effort delivery model, in that it does notguarantee delivery, nor does it assure proper sequencing oravoidance of duplicate delivery. These aspects, including data integrity, are addressed by an upperlayer transport protocol, such as the Transmission Control Protocol(TCP). IPv4 uses 32-bit (four-byte) addresses, which limits the addressspace to 4294967296 (232) addresses. Addresses were assigned to users, and the number of unassignedaddresses decreased. IPv4 address exhaustion occurred on February 3, 2011. 15. IPV6 All addresses are 128 bits Write as sequence of eight sets of four hexdigits (16 bits each) separated by colons Leading zeros in group may be omitted Contiguous all-zero groups may be replaced by :: Only one such group can be replaced 16. 3ffe:3700:0200:00ff:0000:0000:0000:0001 can be written 3ffe:3700:200:ff:0:0:0:1 Or 3ffe:3700:200:ff::1 17. IPv6 uses 128-bit addresses, allowing for 2128,or approximately 3.41038 addresses more than 7.91028 times as many as IPv4 The deployment of IPv6 is accelerating, with asymbolic World IPv6 Launch having takenplace on 6 June 2012 18.
