subject: What Is Dns And The Questions Associated With It [print this page] DNS (domain name service) is utilized to get rid of website names like www.examplecompany.com into numeric IP addresses, which is usually how data reaches the proper destination on the Net. Without that service, users could would have to memorize 12 numeric digit IP addresses so that you can reach the correct website.
For a DNS to operate, web site owner needs to setup his own server or use his Internet service provider's servers. Requests for that IP address with the website are routed to the server. When they are down, users can't attain the website anymore. If ever the servers possess the wrong IP address, users will be unable to access the website as well. It's very important for servers to always be up. If it doesn't work, the website won't have any users.
The way in which DNS works is pretty simple. A user types a website name or a complete URL from a link or bookmark on his browser. The browser then requests an IP address for that website name. The user's computer accesses the server configured on their system, and that's usually his Websites provider's servers. The provider's DNS server forwards that request towards the correct server for your domain. Finally, the server for your website responds when using the correct IP address.
With the way it works, IP address changes tend not to undergo any specific central authority. Instead, DNS is managed locally with the website owner's servers, which are generally done on the website owner's Internet provider's servers. If each one of the servers are down, it translates to his website being down. Due to these risks, it's vital to take measures to assure DNS always stays online and up-to-date.
DNS is among the most critical services to the network. It allows users to get to the most suitable website. However, almost all people spend very little time installing, configuring, and managing. It's usually extremely swift and inexpensive to get servers working. Unfortunately, you can find significant risks using this approach.
One aspect among the high-risk parts is the management of host names and IP addresses. It's really a very manual process. Moreover, DNS that's managed by the database or spreadsheet turn inaccurate and outdated as new entries are placed in manually. New products such as automated IP address management helps save time and significantly reduce the likelihood of not working
One big issue for web owners is where to place the DNS servers. Are the servers supposed to be managed by the owner of the web site? Or should it be outsourced towards the Internet service provider? Most people like to outsource it to the Internet service provider since it's found in most hosting packages.
Outsourcing is helpful for small websites, but it really might get cumbersome to help keep IP addresses in DNS as the quantities of servers grow. Periodically, IP addresses need to be changed manually. A spreadsheet of IP addresses could become out-of-date over time. As a website grows, your website owner should build servers and add items that manage IP addresses automatically to relieve the hazards of errors and downtime.
