Why does DNS matter?

The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.

Big G said that.  Google lately introduced their own DNS service. Yes its the next step in the process of Googles Internet take over Nevermind. Currently the biggest out of ISP DNS provider is OpenDNS www.opendns.com Before Google introduced their DNS service I used OpenDNS because its way faster than my current ISP’s DNS. OpenDNS has many servers inside USA and many other in leading countries. So its very fast if you live in USA or around. But even in Asia for me OpenDNS is advanced for me because its updating instantly while my local ISP takes about 48 hours to update.

So this is not the time to talk about OpenDNS. Now I have configured my computer and router to use Google DNS system you can do the same read this guide- http://code.google.com/speed/public-dns/docs/using.html . I live in Sri Lanka both googledns and opendns doesn’t have servers in my country or neighborhood. So both services connect to USA servers (GoogleDNS only have servers in America with Level3 network OpenDNS got Anycast Routing Technology that Routes your DNS queries automatically to closest server available,). Lets compare this with Namebench DNS benchmark.

Yes its way faster than OpenDNS here is ping test to OpenDNS servers and Google servers-

Note that 208.67.222.222 is the ip of the opendns while the ip 8.8.8.8 belongs to googledns-

And DNSBench benchmark results-

All this tests shows that GoogleDNS better than OpenDNS for now. ITs your decision to move or not!

Well the best choice to explain this is telephone directories. Imagine that you wan to call some one and you know his/her name but not telephone number. So you need a telephone directory to find his/her number. So you can flip the papers of the directory and search for his name and then find the telephone number you need to know.

DNS service acts same like the telephone directory in your home. When you type www.google.com or any web site address in your browser Internet service need to find the ip of the server where google.com situated. So your computer makes request to find the ip address of the google.com from DNS servers. So DNS servers gets the request and then forward us the ip of the web site you need to go.This process works inside of your computer network so you dont get any visuals of ips.

Typically  Internet Service Providers operate their own DNS servers for their customers. They are automatically assigned to your computer if you not manually edit DNS options in your computers network settings. But you can change DNS servers if you like to get more accurate and fast web browsing.

Imagine if your telephone directory is old and un-arranged it takes more and more time to find the phone number. Like the same process the quality of your ISPs DNS server directly affect your web browsing speed. This doesnt means the downloading speed.Slow download and upload speeds doesnt mean your DNS bad.

Come again to the theory of the telephone directory. When you have un-arranged directory it takes more time but it doesnt affect the quality of the call that you make to other party. If you have well arranged telephone directory it takes seconds to find the telephone number but you gets the same quality of the call like previously said.

Bad DNS servers makes slight delay when you request for a web site.

In my next post Ill explain how to optimize your DNS system to be more accurate and Ill do a brief benchmark of newly introduced Google DNS system. SO wait……………….

First of all you need to download this piece of small software to check if your modem suports voice calls ( No matter if the feature disabled in factory settings we are going to activate it. So its worth to check)

Download it here- http://www.dc-unlocker.com/downloads/get/03FpJrhM

And run it after installing.Make sure to exit Mobile partner otherwise the software wont detect the HSPA modem. And after opening it click scan. it will then display the details of the plugged huawei modem like this-

Look there is a option called Voice Feature. In this screen shot it shows enabled because I already enabled it. In your computer it will show Disabled if your have voice calling option if not it will show Not supported.

So if your software shows Voice Feature – Disabled then its the time to enable it. Click the option called Server in the DC-Unlocker software. It can unlock your locked modem too but it require 20 euros. But it doesnt require money to enable voice feature.

In the user name and password field enter these-

Username- Free

Password- Voice

Then click “check login”. SO DC-Unlocker will login free to unlock voice feature. Like this-

Then browse to “Unlocking” section of DC-Unlocker client and click “Activate Voice”. then it will unlock your voice calling feature!

Wait there some other things to done in software section too. You need to update to Voice calling version of mobile partner software because 95% of modems come without voice calling Mobile partner version. Download the voice calling version here- http://www.dc-unlocker.com/downloads/get/LihV26NW

Warning you are going to flash your Huawei modem with this new version. your current connection profile settings will be lost because of new update. And always remember to update the firmware in a steady power sourced computer. Because if your computer gets stuck or powerloss when updating firmware ( which will take 5~15mins) your modems firmware will be corrupted. So be sure you have steady power source to use with your computer when flashing.

After downloading the New Mobile Partner firmware run it and it will update your current firmware. Voila you have new Mobile parnter with voice calling feature like this!

For an example think one wanted to know how to brush his teeth correctly. Then he googles for that phrase “how to brush teeth correctly.” Instead of “Brush teeth correctly”

As a intro webmaster and blogger im mainly focusing on google traffic because I dont trust on yahoo or bing. Because I never succeeded with them. So google indexes your results on top if your content is good and your title is good. Yes title for post on a blog is very important for SEO.

So just follow this tip and see the difference in traffic increasing in yourr tracking tool and earnings.

Things you need-

• A VPS or dedicated server that has at least 128MB memory
• SSH Client , PUTTY for windows operating systems Download it free
• Relaxed mind

Note that there are many Admin panels like Cpanel,Kloxo,ISPconfig,Webmin,Plesk . But I recommend Kloxo (LXadmin) because it runs on even low memory VPS’s that has only 128MB memory and there is built in 2 web servers , Apache  and Lighttpd. Previously there were 2 versions of kloxo panels one is Free version and the other is Kloxo Enterprise.

The free version only had support to only 40 domains run on the same server and Enterprise version can run unlimited domains on one server. But now Kloxo owner LXlabs CEO  K.T Ligesh dead. And the Kloxo is become a freeware So you can now obtain Enterprise license for free.

So if you want more information or want to see demo’s about kloxo please go to their website here.

So lets start-

• First of all you need to install PUTTY and login to your server with it by very easy steps, providing the ipaddress and password given to you buy the hosting company. The default User name is root.
• The you need to install YUM So run these commands on putty-

#!/bin/bash

When your server finishes downloading YUM run this commands to install it-

CVE-2009-2935 Unauthorized memory read from Javascript

Thats what google said about the security vulnerability issue chrome had till yesterday. Well thats not funny and its dangerous like google said,

Severity: High. An attacker might be able to run arbitrary code within the Google Chrome sandbox.

Chrome 2.0.172.43 (click to download for Windows) fixes the issues and another medium-severity issue. Once Chrome is installed, it retrieves updates automatically and applies them when people restart the browser. So don’t need to panic now and install the latest patch that’s it but normally chrome will automatically do it for you.

Personally I recommend Firefox as usual

Getting adsense account is hard these days. specially for Indians they didn’t get approved to this great program easily.But lastly I found a way to get approved on Adsense fast and safe within 24hours. But this is legal way. ATTENTION  Dont reapply if you got banned from adsense one time because its against their terms of service

I AM not guaranteeing approval using this method 100% please mind that. Yes people from India, Africa it doesnt matter  And I havent seen this method shared anywhere else…Unlike some other methods shared like Create a Youtube Channel ,upload videos, Make sure those videos get some hits and apply for Adsense, this method doesnt need much work on your part..

It is as simple as it gets. Here is how…

www.docstoc.com is a website that is partnering with Google Adsense. It is much like scribd.com , where people read documents, ebooks online uploaded by others.

http://www.docstoc.com/doccash/join/

And that is it, you get approved within 24 hours. For ads placed in their site(docstoc.com) (thru Your adsense account), they share a 50/50 revenue…However you can use the adsense account for your sites/blogs and for ads placed in your blogs/sites you keep all the revenue to yourself….

So you can earn some $$$ from docstoc.com (50 % revenue) in addition to using your blogs/sites…

So what are you waiting for ? For those who dont have a adsense account, GO GET ONE…

So is it worth to buy? answer is yes, because .im can be called as instant massaging and its a very short extension. So the official domain registrar is www.nic.im and a domain costs £40 per domain but www.name.com offers one year registration for just $5, But renewal fee can be high after 1 year! .im domains will be really worth to buy and there are nice small letter domains available right now for registration.

I just bought www.Proxify.im for my new proxy site! Buy your domains right now people.
Bye
