DNS stands for Domain Name Service, and it helps in accessing various websites on the Internet. DNS errors usually imply the lack of an active Internet connection. DNS simply translates the address that a person types on the web browser from the human language into the computer language. For instance, an address like www.abclimited.com will be translated into an address like '10.58.255.14'. This translation process makes it possible for the computer to read and understand the address that the user has typed, and then visit that particular website via its server. A DNS error will mean that the machine is unable to access the Internet in order to convert the typed address, and thus the computer will be unable to visit and access that website. Sometimes a computer shows a DNS error only for some particular websites. This can happen due to two reasons. Either the address that has been typed is incorrect, or there is no entry for this website over the Internet. Either of the reasons restrict the user from accessing that particular website. This can greatly restrict a person from using the Internet technology to its fullest. DNS Error FixIn most cases, a DNS error just means that the computer is facing connectivity problems. This could be happening for a variety of reasons, especially if you are connecting to the Internet via a wireless connection. Since DNS transforms the website URL into a numerical IP address, without the DNS functioning properly, the Internet connection will be quite useless. There are a few solutions to this problem though, and none of them are too complicated in nature.
Locate the networking icon on your taskbar (or visit the networking tab from your 'Start' menu), and right click on it. Now select the 'Repair' option. This should be able to fix elementary DNS errors.
Go to the 'Start' menu and select the 'Run' option. Now type 'ipconfig/release' and hit 'OK'. This will release your old IP address. Now you need to type 'ipconfig/renew' and hit 'OK' in order to renew your current IP address.
You even have the option of entering your own DNS settings. If you are using a local wireless connection, you will be informed about the preferred DNS and the alternate DNS. You can alter this setting by going to the 'Properties' of your network connection.
You must also check if all the cables and wires are connected properly. If nothing works, then try using a different machine with the same connection. PS3 DNS ErrorNow that you have got the answer to your question, What is a DNS error?, let us see what the DNS error on a Sony PlayStation3 means. This is one of the most advanced gaming consoles available in the market today, and it also lets a gamer connect to the Internet and play games versus other players online. An active Internet connection is obviously imperative, and the PS3 DNS error message can sometimes restrict the gamer from accessing his online PS3 account. The problem on the PS3 is similar to that of a desktop computer. The DNS error simply means that the device cannot connect to the Internet. In order to fix this problem, some basic knowledge about networking will be necessary. Apart from checking all the cable and wire connections and the network settings, one may even be required to restart the network setup program from the console. If this is unable to fix your problem, then it will not be a bad idea to call your Internet Service Provider (ISP) and ask him what to do. He may give you an alternate DNS that will make your machine work. No matter how advanced the PS3 is, it is still prone to certain malfunctions, a DNS error being one of the most basic errors that it faces. Also see the following:
