DNS what is dns?why it is important

Free DNS
If you've got a tiny personal website for something like holiday photos to share with friends and family, and you don't expect it to grow and don't care about uptime, free hosting is the right choice for you. There's no shortage of free DNS hosting providers to choose from, and each has a variety of different features. Some come equipped with firewall policies, filtering, and rate limiting and blocking to help prevent DDoS attacks. The majority of free services include facilities to manage the records of your domain zone and typically offer Dynamic DNS.
If yours is a casual site or simply something you are doing for fun and it's not the end of the world if the site is down for a couple of days, free DNS services should work for you. On the other hand, if it's a commercial site that is driving your whole business, then you should choose a service that will safeguard your site with better support and uptime. These are the key differences between opting for free DNS and going for a premium service.
Premium DNS
Every commercial website should use premium DNS to guarantee they are both safe and available to their customers. There are distinct advantages of paying for a DNS: improved site availability, faster performance, and minimal security gaps.
Premium DNS involves pointing your domain to premium nameservers and setting up your records on these nameservers.
These are the typical features you should expect from premium DNS services:

• Many premium DNS service providers offer Dynamic DNS (DDNS). DDNS automatically maps internet domain names to IP addresses, allowing you to access your home computer from anywhere in the world. Unlike standard DNS, which only works with static DNS, DDNS is designed to work with changing IP addresses, which is a good fit for home networks.
• Secondary DNS - This premium feature is particularly useful if you manage your nameservers and want a backup or redundancy. A secondary nameserver will ensure that your domain never goes offline.
• Management interface - A well-configured DNS dashboard lets you manage and make updates to your DNS easily online, instead of going through customer services to redirect your DNS using different record types, for example.
• Reporting - Advanced reporting is available with premium services, including analytics that report the source country and record type for queried hostnames.
• Administrative Control - Admin controls let you delegate administrator privileges with ease.
• Two-way authentication - Protect your domain with two-factor login authentication.
• DNS templates - Save time by applying DNS templates to the domain names in your Premium DNS Dashboard. This is useful if you are managing multiple websites.
• Fast Performance - Redundancy - Guaranteed service level agreement for DNS resolution between 99-100% with paid DNS plans.
• Queries per month - Premium DNS services guarantee domain resolution on millions of queries per month.
• Close security gaps - Hackers can use your IP address to point to a malicious IP address to trick users into divulging important information and sometimes even money. Premium DNS hosting provides an additional layer of security for your website and thus additional protection from hackers.
• DNSSEC support - Increase your domain name security with managed DNSSEC. Premium nameservers provide support and security for top level domains to protect them from attacks. Hackers have been known to infiltrate the DNS lookup process, directing users to deceptive sites for password and account collection, for example. DNSSEC is employed to protect domains from any vulnerabilities in the DNS system.
• First-class customer service. DNS can get a bit tricky, so having professional support as and when you need it is invaluable to a smooth running website.
• It is easy to use. Experts and beginners will find the interface for managing their nameservers simple to navigate.

Paid DNS services offer advanced features to manage your DNS, combined with a higher level of support and faster loading times. If you want super fast IP address resolution, you need a premium nameserver.
The fact of the matter is, extremely quick websites leave a good impression. People are impatient online. If you can shave a few milliseconds off the time it takes for people to discover your site via DNS, you might see some marginal gains.
Fast speeds aren't only to impress your site visitors; you'll want to impress Google with your site's loading and availability. If your site loading times aren't up to scratch, your search engine rankings and subsequent click rates could take a hit (DNS capabilities make up a huge part of site load times).

DNS stands for Domain Name Service, and it helps in accessing various websites on the Internet. An error regarding the DNS for any particular website usually implies the lack of an active Internet connection. The purpose of DNS is to simply translate the address that a user types on the web browser from the human language into the computer language.

DNS is used to resolve names to numerical IP addresses, which is needed to route traffic onto the Internet. Whenever a URL is entered into the browser, the beginning part is the website's domain name.

One Website Not Working: try contacting other sites on the Internet to see if the DNS error is particular to one website. If only one site is not working, the problem rests with the one website.

Computer Not Connected: another item to check when a DNS error shows up is to see if the computer is on the local network. Check to see if the home or office router can be reached from the computer. If not, the DNS error is from the computer not being able to connect to the local office or home network.

Internet Connection Down: if no websites are working, it might be because the Internet connection is down due to a faulty cable/DNS modem or the ISP is down. Power off and on the modem. If the DNS errors still persist, contact the ISP.

DNS Errors: in the vast majority of cases, DNS errors have nothing to do with DNS. DNS errors are usually one of the first symptoms of internet or wireless connectivity issues.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

DNS stands for Domain Name System. The Domain Name System (DNS) is a hierarchical distributed 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 participating entities. Most importantly, it translates domain names meaningful to humans into the numerical identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.

you have two ways:-

1. DHCP (Dynamic Host Control Protocol)
2. Manual entry of settings in wireless adapter properties.

1.DHCP:-
In DHCP method you dont have to enter any settings on the wireless adapter. The wireless network which you are connecting will automatically assign an IP Address to you. But to use DHCP it must be supported by your wireless network.

2. Manual entry of settings in wireless adapter properties.
This method is mostly used over wireless Connection in small networks connecting 2-200 computers. In this method you have to obtain the following information from your connection provider.

• IP address (Its format is "xxx.xxx.xxx.xxx")
• Default gateway address (very important)
• Primary and secondary DNS (If not given then you can use "8.8.8.8" as primary DNS and "8.8.4.4" as Secondary DNS...thats free DNS service from google and its very fast)
• Subnet Mask (not needed mostly...automatically generated)

There are two basic types of DNS - primary DNS and secondary DNS, which are generally applied to each newly registered domain. They are name server computers where the record of your domain name is stored. The information on both servers is identical. The two DNS values are usually configured by your ISPor hosting provider and given to you as a very important part of your domain registration order details.

In general, domain names can work with only one name server - the primary DNS. However, practice has shown that a domain name needs to have at least two name servers assigned in order to be available at any time. In case there is a problem with the primary name server, the secondary name server will be able to answer the online request for a particular domain. This back-up requirement has turned into an accepted Internet standard that prevents domain names from going offline.

Hi,DNS is an Domain Name System,It is very important for website creating, I got my dream DNS from this http://www.thewebpole.com/ site ,here only the cheap and best DNS available.

No.1 : If you are on corporate/company LAN, there's nothing much you can do unless you are the system/network administrator. If you are then make the necessary changes in the software at the server level( where open dns and proxy is hosted for access). But beware of your corporate security policies.

No.2 If you are at home or if you have your own internet connection, uninstall or disable open dns and point your system/laptop direcltly to the DNS servers provided by your ISP
