Domain Name
What is Domain Name Registrar?
• Domain name registrar is an organization or commercial entity, accredited
by the Internet Corporation for Assigned Names and Numbers (ICANN) or by
a national country code top-level domain (ccTLD) authority, to manage the
reservation of Internet domain names in accordance with the guidelines of
the designated domain name registries and offer such services to the public.
• Until 1999, Network Solutions was the domain name registry for .com, . net
and .org as well as the sole registrar.
• An end-user cannot directly register a domain and manage their domain
information with ICANN.

Domain Name
Domain Name Registrar:
• Only the designated registrar may modify or delete
information about a domain name.
• The competition that the SRS – Shared Registration System
- created enables end users to choose from many registrars
offering different services at varying prices.
• It is not unusual for an end user to switch registrars which
invokes a domain transfer process governed by specific
domain name transfer policies.
• Examples of Domain Name Registrars: GoDaddy, eNom,
Tucows, Network Solutions, Names4ever, etc.

Domain Name
Domain Name Registry:
• Is a database of all domain names registered in a top-level domain.
• A registry operator, also called a Network Information Center (NIC), is the part of
the Domain Name System (DNS) of the Internet that keeps the database of domain
names, and generates the zone files which convert domain names to IP addresses.
• Domain names are managed under a hierarchy headed by the Internet Assigned
Numbers Authority (IANA), which manages the top of the DNS tree by administrating
the data in the root name servers.
• Most Domain Name Registrars also offer Domain Name Registry.
• The allocated and assigned domain names are made available by registries by use
of the WHOIS system and via their domain name servers.

Domain Name
Confused?
To develop a web site you need:
1.A Domain Name Registrar to register a domain name Domain Name
Registry (Domain Hosting).
2.A Web Hosting Provider/Server Provider to manage the communication of
your domain name with the net.
3.Now a days the process is transparent if you contract a web hosting
provider. (Remember that most companies offer both services at once when
you host your site with them.) GoDaddy, Hostmonster, BlueHost,
Names4Ever, Network Solutions, are some of the reliable hosting providers.
4.Last, but not least: you need to design your site.

HTML?
HTML = HyperText Markup Language is a text and image formatting language used by web
browsers to dynamically format web pages. It consist of “tags” surrounded by angle brackets
and is not considered a language per se.
HyperText means text in the HTML document carries a link to a different location.
Markup means that specific portions of a document are marked up to indicate how they should
be displayed in the browser.
