But computers do not work with real names but with numbers only. So there must be a way to let them understand what we are writing in our browser.

Root Name Server:

A: There are 12 operators for root DNS at 13 unique IP addresses.

A - VeriSign Naming and Directory Services

B - Information Sciences Institute (University of Southern California)

C - Cogent Communications

D - University of Maryland

E - NASA Ames Research Center

F - Internet Systems Consortium, Inc.

G - U.S. DOD Network Information Center

H - U.S. Army Research Lab

I - Autonomica

J - VeriSign Naming and Directory Services

K - RIPE NCC (Reseaux IP Europeens - Network Coordination Centre)

L - ICANN (Internet Corporation for Assigned Names and Numbers)

M - WIDE Project

Each letter from A to M identifies a single IP address.
They are situated in more than 35 countries ( more than 84 locations ), most of them outside the USA. Not all the exact locations of the root servers are known because of security reasons.

The web site www.google.it is translated into 216.239.39.104. In fact if we write this numbers in the address line of our browser, we are redirected the web site google.it

Every web site has a name, of course, like for instance, www.google.it and so on.
Its files are on a server that is a computer in some part of the world.
So when we write a domain name (www.google.it) in the address line of our browser, ( the URL line ) we can see the web site we were looking for.

1)Our computer asks our ISP ( Internet Service Provider - that is the company which provides us the Internet connection ) DNS server what is the number (IP) of this web site. If this server knows it, our computer will be connected with the computer where this site is.

DNS propagation: it is the process which inserts a website IP number into the DNS server around the world. It may take up to 72 hours. This is why a new website is not visible on the Internet before that period of time.

3)If it is not possible to find that address - wrong number or the web site does not exist - our browser will not be able to show us that web site.

Reti di Computer - DNS - Computers Networks

DNS - Domain Name Service - is a system which translates a domain name into numbers.

This numbers are the IP - Internet Protocol - address.

This is how it works:

2)If our ISP DNS server has not that information,it will ask other DNS servers until it finds the IP number which it is looking for. After that, our computer will be connected with the computer where this site is.

There are a lot of computers all around the world acting as DNS servers which have large databases of IP addresses corresponding to domain names.
The whole Internet is divided in zones with a DNS server.

Any computer connected to the Internet has a unique IP address, in the form of XXX.XXX.XXX.XXX, where XXX is an integer between 1 and 255. This number identifies the computer and the network to which it is connected.

Once everything is set, is it time to create a website and get it active and noticed. You can submit your website to search engines so that visitors will come across it during popular searches. You also have the option of paying for advertising and having it show up as links on other websites.

Open up other browsers and test your website. There are some differences in software that may make your website appear fine in one browser but appear different and distorted in another browser. A large amount of website builders forget to do this. This can result in very unhappy website visitors.

Create a Website is Simple

* Get yourself a domain name. Before you create a website, you need a place to put it. A domain name is the name that your site will have and that other people will need to know to access your site. To get a name, you simply have to visit a registrar for domain names (and there are several online) and pay a small yearly fee to get your name registered to you. Once you have the domain name, you can move to the next step.

If you want to create a website nowadays, you can choose from so many methods. As just two examples, there are the so-called “free” services (which are papered with ads) and there are firms that charge large sums to do it for you. However, with a bit of time, effort and determination, you can develop your site yourself by following our several easy steps:

* Design your web pages. This is the most exciting part of the process to create a website. You create the content, layout, appearance, and what your site is trying to accomplish. There are tons of site creating software packages available, from the simple free ones with basic templates you fill in to the creative, professional packages that you can create a masterpiece of a web site with. You can determine what the best package is for your needs.

Create a website and then choose a host for your website if you want everybody to see and access your site. You website needs a place to be stored called web hosts and they usually charge a small monthly fee and they generally offer discount if you make a long term agreement like a year. You should search and find a reliable host which offers you as much space as possible. You can build a beautiful and breathtaking site with lots of bells and whistles.

How to Get a #5 Ranking in Google in 14 Days Starting From Scratch

Did you know that Google gives special ranking bonuses to certain kinds of domain names? It does, and a significant bonus at that. Choosing a domain name that exactly matches the keywords you want to rank for will give your site a great head-start in the rankings.

Yes, it’s true. I landed a brand new blog in the #5 spot in Google for a two-keyword phrase in 14 days. How’d I do it? It’s simple: I chose the right domain name.

Two weeks later I checked the stats for the blog. I was happy to see that I was already getting traffic from Google, specifically for the phrase “dieter’s blog.” I ran the query through Google and, sure enough, my blog was ranked #5. This was in spite of the fact that there are 2.4 million competing web pages in Google’s index for the phrase, and despite the fact that the other pages ranking in the top 10 had a few links into them (You do know that Google favors links above all else, right?).

An exact-match domain name is only the first step, though. Once you have that domain name in place, you have to back it up with links to your site. “Dieter’s Blog”, while certainly a phrase worth ranking for, is not highly competitive, so I was able to get the ranking just on the strength of the domain name and the site’s content. However, for keywords that bring a lot of traffic, you need a lot of links.

In the case of the blog that I ranked #5, I purchased the domain name DietersBlog.net. I then posted 10 unique articles to the blog that I hired a ghostwriter to create for me. I didn’t get any links, or do any promotion of the site at all (I’ll be honest–I got distracted with some other work I was doing).
