USING DNS (Domain Name System) TWEAK TO SPEED UP YOUR BROWSING

FREE PUBLIC DNS SERVICE PROVIDERS LIST THAT PROVIDE FREE DNS SERVICES FOR YOU BUT BEFORE SETTING UP YOUR NEW DNS SERVER SETTING YOU HAVE TO KNOW

WHAT IS DNS DEFINITION


Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. SOURCE: FOR MORE INFO ON HOW ITS WORK SEE WIKIPEDIA.

BEING A MOBILE BROADBAND USER YOU MAY EXPERIENCE SLOW SERVER RESPONSE OR SLOW REDIRECTION WHICH ARE VERY ANNOYING. SO USE THE FOLLOWING TWEAKS TO MAKE BROWSING BLAZING FAST. BELOW ARE SOME FREE DNS SERVER LIST.

Free Fast Public DNS Servers List
The most basic task of DNS is to translate host names such as those.in to IP address such as 74.86.49.131. In very simple terms, it can be compared to a phone book. DNS also has other important use such as email routing. This is my list of better, fast public dns servers and free dns server (as compare to your ISP / DSL / ADSL / cable DNS service providers dns servers). These dns servers are free to all. I was able to improve my browsing speed with following DNS servers. Use any one of the following provider.

Free Public DNS Server =>

Service provider: Google Google public dns server IP address: 8.8.8.8 8.8.4.4 =>

Service provider:Dnsadvantage Dnsadvantage free dns server list: 156.154.70.1 156.154.71.1 =>

Service provider:OpenDNS OpenDNS free dns server list / IP address: 208.67.222.222 208.67.220.220 =>

Service provider:Norton Norton free dns server list / IP address: 198.153.192.1 198.153.194.1 =>

Service provider: ScrubIt Public dns server address: 67.138.54.100 207.225.209.66

HERE IS THE WAY TO CONFIGURE YOU INTERNET FOR NEW DNS SERVER. HERE I AM TAKING THE EXAMPLE OF GOOGLE PUBLIC DNS

  • Microsoft WindowsDNS settings are specified in the TCP/IP Properties window for the selected network connection. Example: Changing DNS server settings on Microsoft Windows 7 Go the Control Panel. Click Network and Internet, then Network and Sharing Center, and click Change adapter settings. Select the connection for which you want to configure Google Public DNS. For example: To change the settings for an Ethernet connection, right-click Local Area Connection, and click Properties. To change the settings for a wireless connection, right-click Wireless Network Connection, and click Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation. Select the Networking tab. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) and then click Properties. Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window. Click OK. Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference. Replace those addresses with the IP addresses of the Google DNS servers: For IPv4: 8.8.8.8 and/or 8.8.4.4. For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844 Restart the connection you selected in step 3. Test that your setup is working correctly; see Testing your new settings below. Repeat the procedure for additional network connections you want to change
  • Mac OS XDNS settings are specified in the Network window. Example: Changing DNS server settings on Mac OS 10.5 From the Apple menu, click System Preferences, then click Network. If the lock icon in the lower left-hand corner of the window is locked, click the icon to make changes, and when prompted to authenticate, enter your password. Select the connection for which you want to configure Google Public DNS. For example: To change the settings for an Ethernet connection, select Built-In Ethernet, and click Advanced. To change the settings for a wireless connection, select Airport, and click Advanced. Select the DNS tab. Click + to replace any listed addresses with, or add, the Google IP addresses at the top of the list: For IPv4: 8.8.8.8 and/or 8.8.4.4. For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844 Click Apply and OK. Test that your setup is working correctly; see Testing your new settings below. Repeat the procedure for additional network connections you want to change.
  • LinuxIn most modern Linux distributions, DNS settings are configured through Network Manager. Example: Changing DNS server settings on Ubuntu In the System menu, click Preferences, then click Network Connections. Select the connection for which you want to configure Google Public DNS. For example: To change the settings for an Ethernet connection, select the Wired tab, then select your network interface in the list. It is usually called eth0. To change the settings for a wireless connection, select the Wireless tab, then select the appropriate wireless network. Click Edit, and in the window that appears, select the IPv4 Settings or IPv6 Settings tab. If the selected method is Automatic (DHCP), open the dropdown and select Automatic (DHCP) addresses only instead. If the method is set to something else, do not change it. In the DNS servers field, enter the Google Public DNS IP addresses, separated by a space: For IPv4: 8.8.8.8 and/or 8.8.4.4. For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844 Click Apply to save the change. If you are prompted for a password or confirmation, type the password or provide confirmation. Test that your setup is working correctly; see Testing your new settings below. Repeat the procedure for additional network connections you want to change. If your distribution doesn't use Network Manager, your DNS settings are specified in /etc/resolv.conf.
Example: Changing DNS server settings on a Debian serverEdit /etc/resolv.conf: sudo vi /etc/resolv.conf If any nameserver lines appear, write down the IP addresses for future reference. Replace the nameserver lines with, or add, the following lines: For IPv4: nameserver 8.8.8.8 nameserver 8.8.4.4 For IPv6: nameserver 2001:4860:4860::8888 nameserver 2001:4860:4860::8844 Save and exit. Restart any Internet clients you are using. Test that your setup is working correctly; see Testing your new settings below. Additionally, if you are using DHCP client software that overwrites the settings in /etc/resolv.conf, you will need to set up the client accordingly by editing the client's configuration file. Example: Configuring DHCP client software on a Debian server Back up /etc/resolv.conf: sudo cp /etc/resolv.conf /etc/resolv.conf.auto Edit /etc/dhcp3/dhclient.conf: sudo vi /etc/dhcp3/dhclient.conf If there is a line containing domain-name-servers, write down the IP addresses for future reference. Replace that line with, or add, the following line: For IPv4: prepend domain-name-servers 8.8.8.8, 8.8.4.4; For IPv6: prepend domain-name-servers 2001:4860:4860::8888, 2001:4860:4860::8844; Save and exit. Restart any Internet clients you are using. Test that your setup is working correctly
  1. AFTER FOLLOWING THE STEP AND FINALLY CONFIGURING YOUR NEW DNS SERVER IT IS NOW TIME TO CHECK WHETHER THE NEW SETTING IS WORKING PROPERLY OR NOT TO DO THAT FOLLOWS THESE STEPTo test that the Google DNS resolver is working:1) From your browser, type in a hostname, such as http://www.google.com. If it resolves correctly, bookmark the page, and try accessing the page from the bookmark. If both of these tests work, everything is working correctly. If not, go to step 2. 2) From your browser, type in a fixed IP address. You can use http://18.62.0.96/ (which points to the website http://www.eecs.mit.edu/) as the URL*. If this works correctly, bookmark the page, and try accessing the page from the bookmark. If these tests work (but step 1 fails), then there is a problem with your DNS configuration; check the steps above to make sure you have configured everything correctly. If these tests do not work, go to step 3. 3) Roll back the DNS changes you made and run the tests again. If the tests still do not work, then there is a problem with your network settings; contact your ISP or network administrator for assistance.
