DNS Hacks for Faster Web Browsing

    What is DNS? Domain Name System (DNS) is like a phone book, but for Internet. DNS translates human-readable computer hostnames, e.g. www.todayisp.com into an IP address needed by the networking equipment to deliver information. In other words, when you open your browser and type an URL in the address bar , e.g. www.todayisp.com, the DNS server translates that URL into a numeric IP address.To understand better, type the IP address from the previous example into your browser's address bar and you will see that it will be transformed into www.todayisp.com.
  Now, if you have a DSL, ADSL, Dial-up or FIOS (fiber-optic service) Internet connection, you must understand that your computer uses the default DNS server from your Internet Service Provider (ISP) and if this DNS server is slow in resolving URLs, you will see that almost all the web pages that you try to access, are loading slow. So, practically it doesn't matter how fast your Internet pipe is. For example, you can be the proud owner of a 1Gbps bandwith, but if the DNS servers from your ISP are slow, your web surfing will be slow too.
  What can you do to fix this? You can call or go to your ISP and complain about this problem, until you get tired probably.
