Network protocles (TCP), (UDP), (DHCP), (DNS) DR:abd alrauoof alshtawi IPv4: IPv4 address is a 32-bit address that uniquely and universally defines the connection of a device IPv4 address is 32 bits long. The IPv4 addresses are unique and universal. The address space of IPv4 is 232 or 4,294,967,296 IPv6 address is 128 bits long Position of IPv4 in TCP/IP protocol suite Abbreviated IPv6 addresses : IPv6 address is 128 bits long: IP Address Classes Class Start End Default subnet mask Class A 0.0.0.0 127.255.255.255 255.0.0.0 Class B 128.0.0.0 191.255.255.255 255.255.0.0 Class C 192.0.0.0 223.255.255.255 255.255.255.0 Class D 224.0.0.0 239.255.255.255 Class E 240.0.0.0 255.255.255.255 Transport Layer TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network TCP is a connection-oriented protocol; it creates a virtual connection between two TCPs to send data. In addition, TCP uses flow and error control mechanisms at the transport level. Transport Layer The User Datagram Protocol (UDP) is called a connectionless, unreliable transport protocol. It does not add anything to the services of IP except to provide process-to-process communication instead of host-to-host communication. UDP runs on top of IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It's used primarily for broadcasting messages over a network TCP vs UDP DHCP The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on internet protocol (IP) networks for dynamically distributing network configuration parameters, such as ip addresses for interfaces and services Why use DHCP? Every device on a TCP/IP-based network must have a unique unicast IP address to access the network and its resources. Without DHCP, IP addresses for new computers or computers that are moved from one subnet to another must be configured manually; IP addresses for computers that are removed from the network must be manually reclaimed Domain Name System (DNS) The Domain Name System is a distributed database with hierarchal structure and serve the basis for name resolution process in TCP/IP network (DNS) converts the name of a Web site (www.vipul.com) to an IP address (65.115.71.34) and vice-versa. This IP is the IP address of a Web site's server, not the Web site's name, and is used in routing traffic over the Internet.
