What you need to know about Operating your Website on DNS Servers

What

DNS (domain name service) is made use of to settle domain names like www.examplecompany.com into numeric IP addresses, which is usually how data reaches the proper destination on the Web. Without DNS, users could require to memorize 12 numeric digit IP addresses so that they can get through the correct website.

Make sure that DNS to get results, the web site owner has to setup DNS on his own server or use his Internet service provider's DNS servers. Requests in the IP address with the website are routed to the DNS server. If ever the DNS servers are down, users can't reach the website anymore. If ever the DNS servers hold the wrong IP address, users will be unable to reach the website anymore. It's very necessary for DNS servers to be up continually. If DNS doesn't work, the website won't have any users.

How

Exactly how DNS works is pretty simple. A person types a domain or a complete URL from a link or bookmark on his browser. The browser requests an IP address with the domain. The user's computer accesses the DNS server configured on their system, that's usually his Online sites provider's DNS servers. The provider's DNS server forwards that request towards correct DNS server for the domain. Finally, the DNS server to the website responds while using correct IP address.

Because of the way DNS works, IP address changes tend not to proceed through any kind of central authority. Instead, DNS is managed locally with the website owner's DNS servers, which are generally done for the website owner's Internet provider's servers. If the entire DNS servers are down, then it's comparable to his website being down. Owing to these risks, it is important to make a plan to make sure DNS always stays on the internet and up-to-date.

Why

New products which include automated IP address management helps save time and significantly reduce the possibilities of DNS no longer working

Where

One important question for webmasters is where to set the DNS servers. Should the DNS servers be managed by the master of the site? Or should it be outsourced to the Internet service provider? The majority of people like to outsource it to the Internet service provider since it's a part of most hosting packages.

Outsourcing can be useful for small websites, nevertheless it could possibly get cumbersome to take care of IP addresses in DNS as numerous servers grow. Periodically, IP addresses should be changed manually. A spreadsheet of IP addresses could become out-of-date as time passes. As a website grows, the website owner could build DNS servers and add products that manage IP addresses automatically to scale back the hazards of errors and downtime.
