Understanding web addresses and domain
names is important to your personal and
Every web page has a URL - the collection
of letters and punctuation in the location
bar at the top of your browser.
Understand Domain Names
A "domain name" is the name of the
location on the Internet of the website you
are visiting. Each domain is owned by some-
For example, the domain name of a web-
site is Job-Hunt.org. Look at the location
bar at the top of the page, and you will see
it there along with more detail about this
actual page's location.
This is what you should see in your
browser's location bar, although you may
need to click in the bar to make it completely
In the image below, the Chrome browser
has bolded the domain name and the letters
"www." Other browser may also bold the
domain name to help you know the webpage
you are viewing.
The letters following the domain name
are the physical location on the computer
publishing this page.
The name of the file that creates this
page is "article_about_domain_names.shtml"
(far right end of the URL). And that page
is located in a folder named "onlinejob-
searchguide" (underlined in the image
Those sections of the URL are separated
by forward slashes, circled above.
The person running the website can name
those sections after the domain name with
any words they choose to use.
If you check the location bar for the web-
page you are visiting, most current web
browsers and smart phones will show you
the domain name of the website you are
Smart phones may only show you the
domain name. It is VERY important to pay
attention to the domain name to be sure
that you are seeing the webpage you want
to be seeing. If the webpage you see looks
like a page from Google, but you don't see

It Is Easy to Register a Domain
Anyone, anywhere - with a credit
card and an Internet connection --
can register a domain name, at a low
People who don't have a Website
often don't have any experience with
domain names and don't understand
how they work. Knowledge is power.
Domain names are one of the
building blocks of the Internet, and
they are a critical part of every Web
Domain names come in many
flavours - Google.com, Verizon.net,
Since domains are so inexpensive,
there are many bogus domain reg-
istrations and, consequently, bogus
Websites. So, understanding domain
names helps you be smarter and safer
on the Internet.
Why Is a "Top Level" Domain
The letters after the "dot" -- as in
"dot com" -- represent the Top Level
Domain (TLD). And .com is the most
common commercial TLD.
The TLD is important because it
may give you a good hint about the
credibility of the Website, and, some-
times, where it may be located. Many
different TLD's exist, including those
for countries, but these are the Top
Level Domains most frequently used:
Most common commercial domain
in the U.S. (but do NOT assume that
all .com's are U.S. based). Open to
purchase by anyone, anywhere.
Another very common commercial
domain, not unique to the U.S. Open
to purchase by anyone, anywhere
Another very common commercial
domain, not necessarily associated
with non-profit status. Open to pur-
chase by anyone, anywhere.
The Country Code for the United
States. Open to purchase by anyone
who certifies that they are in the U.S.
The Country Code for Canada --
there are over 100 other Country
Codes for most of the countries in
the world, e.g. .uk for the United
Kingdom, .ie for Ireland, etc.
Requirements for purchase depend
on what the country has chosen to
Used by educational organisations,
mostly colleges and universities, and

cation in the U.S. Difficult to acquire;

Used by the U.S. Department of
Defense. Closely controlled.

Many other top TLD's have been
introduced since 2010.
What Is a "URL"?
The "URL" is the complete
Internet/web address for a web
page. If you look at the location
bar in your browser right now,
you will see this URL -
This URL tells you that you are
looking at a page named
on a website with the domain named
"job-hunt.org." And "onlinejob-
searchguide" is the name of the folder
on the web server computer for Job-
Hunt.org where the article is stored.
A URL can have many slash marks
and other punctuation in it, but the
second and third slash marks go
around the domain name and the
domain name is at the right end of
that section, just before the 3rd slash
mark - http: / / www.job-hunt.org
/ If you click on the Google+ link
in the "About this author" paragraph
at the bottom on the page, you will
see this in the location bar of your
This URL tells you that you are
looking at a page named "posts" on
the website of "Google.com." And,
in this case, "+SusanPJoyce" is the
folder on the web server for
Google.com where the article is
Notice that the letters in front of
"google.com" in that URL are not
"www." Using the "www" is a con-
vention from when the "World Wide
Web" was new (circa 1995). The let-
ters "www" are not required in a
In this case, the "plus" in
"plus.google.com" tells you that this
is a part of the Google.com website
which has been named "plus." Some-
one running a website can name that
part of the website anything they
Deciphering Three Examples of
1. We could name part of the Job-
Hunt.org website "google.com," and
then the URL might look like this -
The website visited would still be
"jobhunt.org" but some people might
be fooled into thinking they were at
Google.com. You can figure this out
if you remember that the domain
name is at the right end of part of
the URL just before the third slash
mark in the URL.
2. Google could return the favour (?)
by creating a web page that looks
like this -
That would be a section on the
Google.com website that might fool
people into thinking they were at
Job-Hunt.org - remember that the
domain name is at the right end of
the part of the URL between the sec-
ond and third slash marks at the
beginning of the URL.
3. Another example looks something
like this -
Again, the web site you would be
seeing (if this example was real) is
Job-Hunt.org, but you would be on
a page of the Job-Hunt.org website
that happened to be named
Google.com. It's not Google.com -
it's really Job-Hunt.org, but it could
be confusing if you didn't remember
that the domain name is between
the second and third slashes in the
Neither Job-Hunt nor Google will
do this kind of URL, but someone
trying to make you think you were
at Google.com (or at Job-Hunt.org)
when you were at a completely dif-
ferent site, might create this kind of
So, it is very useful to pay attention
to what is in the location bar, and,
in particular, what the real domain
name of the web page is. If it says
that it's a page on Google.com (or
any other website), Google.com
should be in the correct part of the
What Is "Whois"?
Whenever you have a question
about who owns a domain name,
check one of the domain "whois"
(literally, "who is?") sites, like
DomainTools.com. Every domain
name has a "registrant" which is the
owner of the domain name.
When in doubt, contact the
domain registrant to verify who they
are. The domain registration infor-
mation should include the details
about who owns the domain name,
where they are located, and an email
Some domains are "private" which
means the owner pays an extra fee
to keep their name and contact infor-
mation unavailable. This is a popular
option used by scammers, so be wary
of private domain names.
Use of Domain Names
All domains are unique.
No two organisations use the same
domain name, although the only dif-
ference may be the TLD (e.g. job-
search.org vs. jobsearch.com), very
close spelling (e.g. USAJOBS vs.
USSAJOBSS) or hyphens (e.g. job -
hunt.org vs. jobhunt.org) in the mid-
dle.Small changes in a domain name
can make a big difference.
What may look like a little tiny
change to a domain name (like adding
or removing a hyphen or changing
the spelling or the country code) can
mean a very big difference in which
website you are actually visiting. One
may be safe, and one may not be.
A domain name must be associ-
ated with an IP (Internet Protocol)
address to be visible or receive email.
Be Wary of Internet Protocol (IP)
An IP address is the number
assigned by the Internet network
infrastructure enabling the network
to connect with different components
of the Internet. I think of it as the
"machine-language" address that
corresponds to the "human-lan-
guage" addresses we call domain
names. Many IP addresses are com-
prised of a series of numbers in 4
sets of 1 to 3 numbers, ranging from
0 to 255. For example, 220.127.116.11 is an IP
address, and so is 255.255.255.255,
and everything in between.
The new IPV6 addresses are series
of numbers and letters separated by
When you see an IP address in
your browser's location bar, you have
no idea what the domain name is.
Sometimes that's accidental. More
often, the IP address is used to dis-
guise the domain name. So when you
see an IP address in the location bar,
be very careful!
