Something to know about DNS. - sagher - 01-27-2017
Hello evryone. Do you know about DNS? What is DNS. and how it's works? DNS is Sub name of The Domain Name System essentially just converts an IP address into a more human friendly form by making it easier to remember. Such as www.post4vps.com or 104.31.79.204.
To your browser, they are both the same thanks to the magic of DNS. What DNS does is to map and match domain names like www.post4vps.com to an IP address like 104.31.79.204 When you type www.post4vps.com into a browser, the computer asks a DNS server on your local network or the internet if it can find an IP address that it can match with that domain name (most browsers have a small bar at the bottom that will display a message saying "looking up www.post4vps.com ."). The said DNS server will answer back with the IP address if it has mapped and matched it, and if not, it will then contact other DNS servers on the Internet until it finds the address it's looking for (or throws an error if there is no match). The whole process generally takes will only take a few milliseconds.
ISP's generally assign each customers router to a DNS server to contact when the connection is first made. Your router will receive DNS requests from your local network and pass them on to the ISP's server. Without any DNS servers, your web browser would be unable to convert domain names such as www.post4vps.com into an IP address, and you would not be able to access any web pages.
In reality you don't have to have a domain name to host a website. If your home computer is connected to the Internet with a web server such as Apache, nGinx or Hiawatha, and you have created a web page in your web servers root delivery directory, anyone else on the internet can access that web page by typing your current IP address into their web browser. Nowadays you will find you get your routers admin login (hopefully) page, as your router has a very lite weight web server built in! You will always have to configure your router with port forwarding which, in short, allows a connection to bypass the routers web server and go directly to your computers web server on the given ports you forward. But if you want to host a website that people will actually visit though, it really is best to get a domain name.
In order to get a domain name, you will need to register with one of the many domain name registration services (such as noip.com, or dot.tk), Although Network Solutions is the Great DAD of all of them, there are so many other registrars which offer very competitive pricing. Usually you get a domain, for a fee, on a monthly, yearly or multi-year basis. The Internet Corporation for Assigned Names and Numbers governs all domain names on the Internet, and domain registrars have special permission, by way of obtaining a license from ICANN, to lease them to you for a period of time.
Once you have chosen a domain registrar service, you will obviously choose the domain name you want and search with your chosen registrar to see if that particular domain name is already taken, so there is no chance of two people owning post4vps.com for example. Fees for domain registration will vary greatly, from a few pence/cents (godaddy.com, at the time of this writing, are offering .co and .co.uk for £0.01!), right up into the millions;
From Wikipedia;
Insurance.com $35.6 million in 2010.
VacationRentals.com $35 million in 2007.
PrivateJet.com $30.18 million in 2012.
Internet.com $18 million in 2009.
360.com $17 million in 2015.
Insure.com $16 million in 2009.
Fund.com 2008 £9.99 million.
Once you have registered your domain name, you can use the domain registrars website to map and match your newly purchased domain name with your computer's IP address. From this point on, anyone who enters your domain name into a browser will be directed to your IP address and subsequently your web page/site! Simple really
!So guys there you have it, what DNS is and how it all works. Thanks for reading and I hope you've learns something new today and I will be back with more information all the time.

we need a tl;dr :c
Didn't go through it but took a few glimpses and I think you wrote some very good info there, thanks for telling us!

For free domains,
eu.org is the best. Pretty good sum up. Would be a lot more readable if you wrote with bullet points and used bold on main points.
Thanks

ok @rudra i can edit it on your request. i don't do this because of some extra facial on text some boards are not accepting it. and remove encoding.

I guess you could always use the full edit mode. All the supported bells and whistles are there. Actually that format would help anyone have a gist pretty fast. And that in turn might encourage to read it all, more times than you might guess.
