The Top Level Domains (TLDs) in use today are a relic from the
first days of the World Wide Web (WWW). The idea of grouping web
sites into domains was to organize sites according to their
purpose, so users (at least in the US) would know whether they
were visiting an educational (.edu), military (.mil),
governmental (.gov), or commercial (.com) website. In the mid
1980s, 250 Top Level Domains were introduced: 244 country-code
TLDs (ccTLDs) and six generic TLDs (gTLDs) (.arpa, .com, .edu,
.gov, .mil, and .org). The ccTLDs and gTLDs have dominated
the Internet ever since.
gTLDs (generic TLDs)
Generic TLDs (.com, .net, .org,
.edu, etc.) will only be delegated by ICANN to a selected
group of companies against high costs. It is currently
extremely difficult to register gTLDs. The rules to register
domain names under gTLDs are different for each registry.
The authorized registrar is ICANN. The traditional gTLDs where created to create an
artificial limitation of availabe domain names
available on the web. The introduction of corporate and
public TLDs will change all this.
ccTLDs (country code TLDs)
These two letter labels
are reserved as country code identifiers under ISO 3166. Two
character codes will only be delegated to a competent
government authority associated with that code. It is not
possible to register any ccTLDs. The authorized registrar is IANA.
cTLDs (corporate TLDs)
Corporate TLDs are delegated by approved and accredited TLD registrars to corporations that want
to secure their name on the Internet. Registering cTLDs is
simple (for corporations only). UN1D is such an approved and accredited TLD registrar. Click here to

pTLDs (public TLDs)
The registration of a public TLD is available to everyone and is based on First Come, First Served (FCFS) system through many authorized TLD Registrars such as UN1D. Click here to
register your public TLD now. In addition, many Public TLDs Registrants have on-line registries available that allows anyone to register domain names (SLDs) under that TLD.
- There is also an altogether different category, called
dormant TLDs. These TLDs are registered and reserved for future use, dTLDs
are not available, and there are no Domain Names associated
with them. Any newly registered TLD is a dormant TLD by
default. However when the TLD is resolving domain names, it is alive. It has become one of the 4 kinds of TLDs
mentioned above.
