DNS name server + name resolution with BIND9

As soon as you as an entrepreneur, freelancer have two servers in your company and operate more than five workstations, network printers, you will benefit from the name resolution of your own DNS name server. As a school or training institution in particular, you participate with a growing number of digital courses from a name server.

  • You can easily add new computers to the existing domain structure.
  • Your computers, printers, servers are easily recognizable by their names.
  • You benefit from our experience at BIND9 and are guided through the process.

There are computers behind every IP address on the Internet and in corporate networks that are to be addressed. In any case, this is possible with the IP addresses, but does not correspond to the general procedure of contacting the hosts with speaking addresses. IP addresses are far too unwieldy and difficult to remember, because you have a structured number memory. This is remedied by the Domain Name Service (DNS), with which the hosts, especially hierarchically, can be assigned to entire domain groupings.
Web hosts and domain registrars already offer their name servers and corresponding web portals so that you can assign the appropriate domain and host name to the IP address of your website or server.
This is practical if you have a manageable number of computers or websites and you don't have high demands on the DNS offered. As soon as you either want to use special configurations in DNS such as DNSSEC or there are several computers or servers in your network that should not be visible from the Internet, you cannot avoid a name resolution. As four decades ago, you could still manage the latter, also by adapting the /etc/hosts locally on each computer. But even with 5 computers or more, this becomes so confusing that a separate name server is always worthwhile, even in small company networks.
If you would also like to equip the internal computers in your network with your domain plus host name via the DNS server of your provider, your internal computers would be accessible worldwide and your firewall would no longer make sense. However, given the scarcity of IPv4 addresses, this scenario would be unrealistic. Which justifies the need for your own internal name server.

IT-LINUXMAKER relies on BIND9 and installs your own DNS resolver, caching name server or hidden name server. To ensure that your DNS data are neither manipulated nor come from another source, we recommend using Domain Name System Security Extensions (DNSSEC).
