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

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.
