P a g e | 1 ASSIGNMENT 1 ANSWERS I. Identify the purpose and types of DNS, including explanations on how domain names are organized and managed. (P1)
1. The concept of DNS.
a. What is DNS?
Domain names are converted into IP addresses by the Domain Name System (DNS), which browsers
use to load internet pages. Every internet-connected device has its own IP address, which other
devices use to locate the device. DNS servers allow people to type normal words into their browsers,
such as Fortinet.com, nytimes.com, or espn.com, without having to remember the IP address for
each website. Without DNS, the Internet would collapse, as people and machines would be unable to
access Internet servers via familiar URLs.
Each Internet-connected device has a unique IP address that other machines use to locate the device.
DNS servers eliminate the need for humans to remember IP addresses like 192.168.1.1 (in IPv4) or
more complex newer alphanumeric IP addresses like 2400:cb00:2048:1::c629:d7a2 (in IPv6).
Figure 1: What is DNS?
b. The purpose of DNS.
DNS is an acronym for Domain Name System, which is a name resolution system for the Internet that
was created in 1984. It is the only system that permits the corresponding configuration between IP
address and domain name. Domain Name System (DNS) is a hierarchical naming system for
computers, services, or any resource connected to the Internet or a private network that is based on
a distributed database. Most importantly, it converts human-readable domain names into numerical
identifiers for networking equipment, allowing devices to be located and connected globally. DNS,
which functions similarly to a network "phone book," is how a browser can translate a domain name
P a g e | 3
Figure 3 : DNS Types
There are top three DNS types:
DNS queries: DNS query is also referred to as a DNS request. It is a request for information sent from
the user's computer in order to obtain the IP address of a DNS server. This indicates that the DNS
client is querying the DNS server for the IP address associated with that domain. There are 3 types of
simple queries in the DNS system:
Recursive Query:
A DNS client provides a hostname in a recursive query, and the DNS Resolver "must" respond with
either a relevant resource record or an error message if it cannot be found. The resolver initiates a
recursive query process, beginning with the DNS Root Server until it locates the Authoritative Name
Server, which contains the IP address and other information for the requested hostname.
Iterative Query:
A DNS client provides a hostname in an iterative query, and the DNS Resolver returns the best answer
it can. The DNS resolver returns the relevant DNS records if they are in its cache. If this is not the
case, it directs the DNS client to the Root Server or another Authoritative Name Server that is closest
to the required DNS zone. The DNS client must then retry the query against the DNS server to which
it was referred.
Non-Recursive Query:
A non-recursive query is one for which the DNS Resolver knows the answer. It either returns a DNS
P a g e | 4
record immediately because it already has it in the local cache, or it queries a DNS Name Server that
is authoritative for the record, indicating that it definitely has the correct IP for that hostname. There
is no need for additional rounds of queries in either case (like in recursive or iterative queries).
Rather, the client receives an immediate response.
Figure 4: DNS Queries
DNS servers: DNS servers convert domain names into IP addresses. It takes requests from humans
and converts that into machine IP addresses that make it easier to reach the origin server. There are
3 types of DNS Servers in the DNS system:
DNS Resolver:
DNS resolver is also called a recursive resolver, it converts the hostname into an IP address which is
machine friendly. This server is designed to receive queries from web browsers and other
applications. This resolver receives a hostname in the form of www.sample.com and is also
responsible for tracking the IP address for that hostname.
DNS Root Server:
The root server is the first step in the process of going from a hostname to an IP address. The DNS
Root Server determines the Top Level Domain (TLD) from the user's query — for example,
www.example.com — and provides information for the.com TLD Name Server. In turn, that server
will provide information for domains in the.com DNS zone, such as "example.com."
The DNS uses 13 DNS servers and that is based on a constraint of Internet Protocol version 4. There
are 13 root servers worldwide, indicated by the letters A through M, operated by organizations like
the Internet Systems Consortium, Verisign, ICANN, the University of Maryland, and the U.S. Army

- Mail exchanger record (MX Record): specifies the domain's SMTP email server, which is used
to route outgoing emails to an email server.
- Name Server records (NS Record): specifies that a DNS Zone, such as "example.com," has
been delegated to a specific Authoritative Name Server and provides the name server's
address.
- Reverse-lookup Pointer records (PTR Record): enables a DNS resolver to provide an IP
address in exchange for a hostname (reverse DNS lookup).
- Certificate record (CERT Record): stores encryption certificates—PKIX, SPKI, PGP, and so on.
- Service Location (SRV Record): a service location record, similar to MX but for different
communication protocols.
- Text Record (TXT Record): Usually contains machine-readable data such as opportunistic
encryption, sender policy framework, DKIM, DMARC, and so on.
- Start of Authority (SOA Record): this record appears at the beginning of a DNS zone file, and
indicates the Authoritative Name Server for the current DNS zone, contact details for the
domain administrator, domain serial number, and information on how frequently DNS
information for this zone should be refreshed.

3. Explanation of how domain names are organized and managed.
a. How domain name is organized?
Domain names are organized in special databases. These databases are part of the global domain
registrar system. DNS handles the mapping of IP addresses to human-readable hostnames (Domain
P a g e | 7
Name System). The domain names are a mix of second-level and top-level domains. The second-level
domain is the domain's human-readable hostname. The other type of top-level domains is classified
into three types: gTLD, ccTLD, and nTLD. For example, the domain name of our website is
“https://domain.me”.
Figure 7: How domain names are organized
b. How domain names are managed?
Domains are under the authority of ICANN, which administers the top of the DNS tree by
administrating the data in the root nameservers, and is in charge of domain names. the Internet
Corporation for Assigned Names and Numbers which is responsible for creating new and maintaining
current top-level domains. All other domain name authority is delegated to other domain name
registries, and a complete list may be seen on IANA's website. IANA assigns country code top-level
domains (ccTLDs) to national registries. Every Domain name consists of at least two parts – an actual
name and the TLD or Top-Level Domain.

1. Communication protocols.
a. Defintion
Communication protocols are formal descriptions of digital message formats and rules. It exchanges
messages within or between computing systems. Communication protocols are important in
telecommunications systems and other systems because they ensure message consistency and
universality.
b. The purpose of communication protocols
A communication protocol is a set of rules that enables two or more entities in a communications
system to exchange data using any physical quantity variation. The protocol defines communication
rules, syntax, semantics, synchronization, and error-recovery techniques.
A communication protocol is a formal description of digital message formats and rules. They must
exchange messages within or between computing systems. Communication protocols are important
in telecommunications systems and other systems because they ensure message consistency and
universality.
