Answer 2

It's an alternative method to connecting to the network that is the internet. When you connect, by default you'll be connecting to the DNS servers provided by your internet service provider (ISP). People generally use the OpenDNS servers in hopes of speeding up their web surfing.

There is some controversy over using OpenDNS, however, as a mis-typed URL will take you to an ad page with suggestions for where you may have wanted to go.

Answer 3

In order to surf the Internet, you need to know a website's URL or IP address. For example, Google website is www.google.com or 64.233.167.99. You can enter either the URL or IP address in to your web browser's address bar and you will be taken to Google's website. People find it easier to remember URL's for obvious reasons. On the Internet, there are large servers which sole job is to connect you to the right website. It takes your URL and finds the corresponding IP address. Once the server finds the correct IP address, it can connect you to the desired website. When you enter a website, your computer sends out a request to download the website. The request is picked up by one of these servers, called DNS servers, and it then connects you to the right website - kind of like a Internet operator. There are several DNS servers. Usually, you use your Internet Service Provider's DNS servers. However, hackers sometimes target these servers. So, you might want to go to mybank.com but, if hackers manage to take over the DNS server, you can be taken to one of the hacker's fake websites which could trick you in to giving up your id and password. OpenDNS is organization which has its own DNS servers, which they claim are very well protected from such atttacks. In addition, they also claim their servers can connect you faster than other servers, which can speed up your Internet surfing. To some degree both claims are genuine.

DNS stands for domain name system, a large reference for translating domain names, such as yahoo.com into IP addresses. The domain name servers on the Internet are tightly controlled for obvious security reasons.

It is possible for anyone to register a domain name and get a corresponding IP address. The registration costs money, and a static (non-changing) IP address costs extra.

When you have DSL or cable modem, your IP address gets dynamically assigned by the service provider. So an address can and does change.

Suppose you have a web site that you are hosting, or a game server. How are your friends going to find your server if its IP address changes? OpenDNS to the rescue. This is a free service where you (or your router, automatically) registers its IP address and a name by which your friends can find your server. If your DSL modem starts up it reports its IP address to opendns.

Unless you are hosting something, there is no need for a domain name or opendns.

More details in the included link. After reading the articles (eg slashdot comments) linked to on the page, I must admit, I'm not terribly impressed or likely to use it any time soo.

OpenDNS is a free DNS resolution service. It provides the following two recursive nameservers for public use:

* 208.67.222.222 (Resolver1.OpenDNS.com)
* 208.67.220.220 (Resolver2.OpenDNS.com)

OpenDNS offers DNS resolution for consumers and businesses as an alternative to using their Internet service provider's DNS servers. By placing company servers in strategic locations and employing a large cache of the domain names, DNS queries are processed much more quickly[1], thereby increasing page retrieval speed
