Main Topics
Browse All TopicsI have a few questions.
When does a router comes into picture and when does a DNS server comes into picture?
Let's start with a real time scenario.
I want to start a new website. I have my own powerful servers and routers. So i don't need any hosting.
I have an ISP service provider with 50 static ip addresses.
The only thing i need is a domain name.
So where should i start now?
I think i should register a new domain name with a comany who manages that. who would be that company?
From that point onwards, If some one types for example www.mycompany.com what's would be the network path of that request. Where would the request go? how would they access my website.
I would really appreciate if some can give me a big picture of how all this works out?

www.godaddy.com is cheap and good for registeing domain names..... you will need to change your mx record to point to your servers
First you have registered your domain name (at www.godaddy.com or others suggested). This means that you Own the name. No one else on the internet can use it. Next you need to have DNS regestred to point to the IP address of your webserver. your ISP may do this, but if they charge a fee there is some free DNS services like http://www.zoneedit.com/ (godaddy does also offer that service) Once you have your Domain Name registered, then you can go to your ISP or zoneedit and use it to manage your DNS records. this is actually how when a user looks up www.mycompany.com and it returns the IP address of your web server.
as far as you are conserned you can ignore the routing. The routers actually do the routing of the traffic and you do not need to worry about it as long as your Web server is on the Internet and not behind a router that you manage.
What is DNS
http://en.wikipedia.org/wi
http://computer.howstuffwo
You will have to setup a webserver on your server and then host your site on that system.
So once you have registered your domain name with one of the registrars like the ones given above, you can then point your domain name to the IP address of your server.
So when someone types in www.mysite.com in thier browser window, that browser would contact the root server to get the corresponding IP, and the request would come to your server.
generally how things work is there is a bunch of DNS servers around the internet, these servers are usually owned by ISPs. These DNS servers have databases that have 'mappings' from the IP address to a domain name. Each DNS server is assinged which domains it has 'authority' over and therefore who has the 'rights' to change the IP address for any domain name. These DNS servers to periodioc replication of their databases with each other so if the DNS server that has authority to change the IP address of a domain changes it, the changes are replicated throughout the internet durring the process. Generally this can take 24-48 hours to complete across the globe.
The users who want to open a web page have been assinged a specific DNS (or two or more) server (generally by their own ISP) to use in order to handle these lookups. when the user types in www.mycompany.com the computer asks the DNS server that was given to it by the ISP what is the 'IP address for www.mycompany.com' the DNS server (if it knows it -if it does not then it may look to other DNS servers to find out what it is, depending on the rules set up in that particular DNS server) returns the ipaddress to the computer trying to browse the internet, then the routers do all the work of getting the data to and from the client IP and the web server IP.
That was a very quick and dirty approch, I hope it helps.
Thrasymachus,
This is what exactly i wanted which is 'under the hood'. That's very impressive. Thanks for your response. I have a few more related questions. When does the router comes into the picture? we are a small company and we have our dns server and router? what's the use of having our own dns server and routers when the ISP has it? and a big question? Who these internet service providers and what's a backbone?
Thanks,
Kaiser
this is a great site for explaining how tons of things work. here is their article on the internet:

DNS is like an address book. Routers are like the road signs along the way.
each network has a series of IP addresses within it that is defined by a subnet mask that generally look something like 255.255.255.0
the subnet mask defines which IP address are within that particular network. each computer has an IP adderss that coresponds with a Router. this is generally called the Default gateway. The router has a list of routes in witin it so when it recieves a packet from a computer or another router is knows where to send the packed next in order to get to it's ultimate destination. (Should it take a right or left turn)
Routers use routing protocols to determine what the best path is to get the packet to it's destination.
You would probably have one router that your Web server uses as it's default gateway and it sends the packet to your ISP and then it gets routed and routed until it gets to where it needs to be. If you want to see this in action bring up a command prompt and type 'tracert google.com' you will get a series of hops and each one is a router. the first hop is probably your default gateway and the last one is one of Google's web servers.
If you are a small company I would suggest that there is not a huge benifit to having your own DNS server (for external addresses - you may still need a DNS for internal ones. but that is a sepperate issue) As I stated you still need one Router to route all your internal traffic to the ISP (and possibly doing NAT, but that is a sepeate question as well)
I do not understand exactly what you mean by who theses ISP are? a backbone is generally the linking of all your network traffic through hubs/switches.
I hope that helps sorry for the bad spelling

If you register your domain at a site like www.godaddy.com or www.1and1.com (under $10 year per domain), they will be able to HOST your domain as well. Hosting can be as little as $5 a month.
So to get a domain name at a low price, go to one of the sites above.
If you want to HOST the domain on your own server, you need to set that server up as web server. One way is with IIS (part of Windows server). There are some downsides, however, regarding need for bandwidth, protecting from Viruses and DOS attacks and the general on going maintanence.
It may be smarter to let 1and1 or godaddy host your site for now and take over the protection and management of the server.
With this scenario....you can develop the website locally (with Frontpage, Dreamweaver or other software), and upload to the website . . . or with the free wizards on the hosting company's site.
Once the site is registered , the world will find www.mydomain.com within 12-48 hours.
