• IP has the task of delivering packets from the source host to
the destination host solely based on the IP addresses in the
packet headers. For this purpose, IP defines packet structures
that encapsulate the data to be delivered. It also defines

of administrative autonomy, authority or control within
the Internet. Domain names are used in various networking
contexts and for application-specific naming and addressing
purposes. In general, a domain name identifies a network
domain, or it represents an Internet Protocol (IP) resource, such
as a personal computer used to access the Internet, a server
computer hosting a website, or the web site itself or any other
service communicated via the Internet. In 2017, 330.6 million
