Use Open Dns For Better Performance

Use this DNS so that u can get DNS Resloving faster than your ISP Provides you.

These DNS are open

208.67.222.222

208.67.220.220

these are whose DNS.

OpenDNS is a better DNS service. Its make your Internet safer, faster, smarter and more reliable. It's free, and there's nothing to download

anyine tried this?? working better for anyone??

How does open DNS make anything safer, smarter, more reliable, etc., etc.?

Let us all understand the DNS.

DNS is Domain Name System. The DNS server's job is to translate an http address to a real IP address - something like a phone directory. There are many DNS servers all over the world that do this job and all are sync'ed up. When a new company wants to register itself with a new domain name (say www.<newcompanyname>.com), it pays the domain registration fee for the period (max = 10 years) and then if the domain name is available, it is given to that company. Internally it is given a real world IP address. This DNS translation is stored in a file called 'hosts' in a DNS Server in the directory /etc (Unix) or %SYSTEMROOT%\system32\drivers\etc (Windows Server NT/2000). The hosts file has entry like this:

www.<newcompanyname>.com <ii>.<jj>.<kk>.<ll>

where <ii>.<jj>.<kk>.<ll> is the IP address of the server which holds the website www.<newcompanyname>.com

When we setup our router for the internet, we have two options:

- obtain DNS address automatically: In this case the ISP provides the DNS server address.
- specify a known DNS server address (primary and secondary): We provide the DNS address. It could be our own DNS (private DNS) or an open DNS.

So when you type www.<newcompanyname>.com, the DNS server tells you the IP address.

There is another part of the DNS job and that is resolving the IP address. OK, you got the real IP address. How do you know where it is located? The requester has raised a 'query' that I want to visit this website. The DNS job is to direct the user to that site. This is where IP resolution comes into picture.

a) The resolver tells the system that the server with the desired address (website) is here in this part of the world located here.

OR

b) It will tell that the desired server (website) is not here. Go to the next DNS nearby and check. Thus the internet query hops to the next DNS server and checks again.

This hopping continues till the address is found.

Common sense tells us that the less hopping we have to do, the quicker we will find the address. Contrary to all popular beliefs, open DNS does not necessarily save you this hoppping. In most cases it will but by a few hops only.

But what the open DNS system has done is that it has placed a cluster of servers in strategic locations where internet traffic is heaviest. This cluster of servers helps in resoving the address very quickly - much quicker than the ISP's DNS.

This helps in hitting the page quickly. Also open DNS is the first DNS to be updated in case of a new domain registration.

Open DNS does have some phishing filters but that does not amount to safety. It also has 'automatic typo correction', e.g. if your type 'www.google.cm' it will automatically correct it to 'www.google.com' and this also improves speed as an unnecessary query is eliminated.

After the website is found, the rest of the speed depends upon:

a) internet speed provided by the ISP
b) the network traffic in our ISP and circuit
c) the network traffic at the website server
d) how powerfull is the website server in handling large traffic

Open DNS or private DNS will play no further part from then on.

When I re-read the post, it felt like I was challenging.

The above post is in fact explaining how it is safer, faster, smarter, reliable, etc. But it also goes on beyond, to help you know and understand what to expect. People should not expect that their speeds will dramatically increase by open DNS.

What is DNS: Where OpenDNS fits in?

OpenDNS is the world's most intelligent DNS service. Our global network and our software work together symbiotically to offer a set of features custom-tailored to you, without requiring you to buy any hardware or install any software.

How its reliable: Global redundancy

built a self-healing network across two continents to give you the most reliable DNS service on the planet. it use multiple carriers at every site to ensure full redundancy of our Internet bandwidth. That bandwidth then feeds into a cluster of servers, which is constantly balancing the load across itself so your DNS request is answered in the fastest way possible. it do this for you and every one, about 30,000 times per second (and growing).

How its faster: Global footprint

OpenDNS has servers situated strategically at the most well-connected intersections of the Internet. Unlike your ISP, our network uses Anycast routing technology, which means no matter where you are in the world your DNS requests are answered by closest datacenter. Anycast routing also means that you are automatically routed to closest datacenter in the event of maintenance or downtime. This makes your Internet faster and more reliable.

How its safer: Our phishing protection changed the industry

OpenDNS operates PhishTank.com, the most accurate and timely source of phishing data on the Web. it protect you from phishing scams by blocking the fraudulent sites from resolving on your network by incorporating PhishTank directly into its system.

How its smarter: Understand your network, then take action

it give you a Dashboard for your DNS that provides detailed stats and analytics. This helps you understand what's happening with your network and see trends before they become problems. But knowing is only half the battle. So it give you the tools to take action.

How its free: We make money just like Google and Yahoo

People frequently ask how can offer such a fantastic service without charging a dime. OpenDNS makes money the same way Google and Yahoo do — by showing relevant ads when its shows you search results. its number one priority is to deliver the best possible user experience, which means you won't find any pop-ups, pop-unders, or anything like that around here.
