The Domain Name System (DNS) is one of the most important services on the Internet.
Without it, websites cannot be visited nor can there be any communications
via email.
To ensure the reliable accessibility and constant short response time of your domain(s), Innter.Net© employs a network of worldwide distributed DNS servers.
Advantages of distributed DNS servers:
The decentralized DNS operation of Innter.Net© not only drastically increases the availability of your websites. It also noticeably decreases the response time (the time it takes from the input of the URL in the browser until the page starts appearing). This is particularly noticeable when accesses are made from overseas, i.e. when international visitors wish to access your website.
Due to physical global distribution of DNS servers, the server located
closest to a request is automatically able to reply. Supposing your website
has a visit from the USA, one of the Domain Name Servers located in the USA
can react immediately. Without this distribution, the data stream for the
DNS request may have to travel halfway around the world to reach a DNS
server.
Reduced response time:
Without distributed DNS servers, data takes a much longer time to transfer
and is less stable. A user will notice that it will take a longer time to
get into a site and will not wait for your site to load if your competitor
site will load at a faster rate.
What is the Domain Name System:
The DNS is a distributed database, which manages the name space on the Internet and translates IP addresses to names (domains) and vice versa. This is comparable to a telephone book, which resolves the names of participants into their telephone numbers. The DNS thus offers a simplification, because humans can remember names far better than a string of numbers.
The identification of computers on the Internet is based on IP addresses. These consist of groups of numbers, which are separated by full stops (e.g. 151.140.4.22). From a technical point of view, IP addresses suffice to address websites and to send emails. However, IP addresses aren't user-friendly, are difficult to remember and don't contain any extra information. This is why a naming structure was introduced, which should simplify navigation on the Internet - the Domain Name System (DNS).
DNS structure:
The DNS is a hierarchical, decentralized system used to manage names, which distributes responsibilities and ensures the uniqueness of these names. This is true for IP addresses as well as DNS names. This occurs via a tree-like structure of the name space. The root of the tree branches out into various branches, the Top Level Domains (TLD). These in turn branch out into further branches, the Second Level Domains.
