Google Public DNS
Google throws out a new stuff to the public-Google Public DNS.Somebody may not know what DNS exactly is.Here’s the simple explanation:
The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An often used analogy to explain the Domain Name System is that it serves as the "phone book" for the Internet by translating human-friendly computer hostnames into IP addresses. For example, www.example.com translates to 208.77.188.166.(Wikipedia)
In the real world,every website/server will have an IP address.However,in order to easily access the site,we normally type in the domain name to visit it and the domain name server will translate it into that specific IP address.After all,we could get what we want to get.
Many ISPs will always provide some DNS service to their customers,even automatically configured.However,Google Public DNS could give more compared to other DNS service:
- Speed up your browsing experience.
- Improve your security.
- Get the results you expect with absolutely no redirection.
Google has a broader network all over the world.Thus,it will direct you the closest DNS server once you set Google Public DNS as your priority DNS.
To try it out:
- Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers or
- Read our configuration instructions.
I previously tried OpenDNS for some while.It is also an independent service provider with quite a lot of credits from the clients.But the DNS servers are mostly located in Europe and America,the users in Asia would have delay because of the geographic conditions.Google eliminates the issue since it has several DNS servers in Asia.
I have used Google Public DNS for 3 days.It works as well as what it says.I’m so happy to see that we are having more alternatives.Thumb up!
