System-NS as it is

    System-NS was planned as a service for personal use. But, in the process of creation, we (developers) were a little “carried away” and our project grew into a public resource.

    This is how it all happened .

    We needed secondary DNS services to ensure the availability of our servers even if the wizard is unavailable. Having made sure that the solutions provided on the market do not suit us, in November 2012, active work began. We wanted to make a service that would update and configure slave zones on all servers as quickly as possible and allow us to refuse to install and configure additional central administration tools or to statically configure zone updates / additions from a predefined list of IP addresses of master servers.

    Thus, on January 21, 2013, the project appeared on the network and began to gradually gain an audience. Initially, only the secondary DNS server service was available, then we sequentially added dynamic and managed DNS.

    The domain information storage system that we selected when developing secondary allowed us to read and edit a large number of records almost instantly, which prompted us to create dynamic. Having completed the development and testing of dynamic DNS, the question arose: “What next?”. Someone from the staff (who specifically, no one remembers, but everyone believes that it was precisely his idea) said: “What the hell do we rule our domains with our hands, let's make an interface for managing domains!” (I'm sure of course that the idea was exactly mine). After implementing a simple interface for editing domain records, we added the ability to transfer the secondary domain to managed, deciding that some of our users would be interested. In the process of use, we were faced with the need to import domains through a ready-made zone (in the form of a bind file for example) or even simply import via AXFR. This functionality was useful to us many times, so we decided to add it to the public service.

    Now briefly about each of our services, more precisely about their features.

    Secondary Fast, convenient and easy one-click zone transfer. It works according to the scheme: a request of the form “who serves the domain” to the root servers, then each server from the list is polled and an AFXR transfer is attempted until the first response.

    Dynamic Instantly flush the cache after updating the IP address. Implemented dynamic DNS management through API calls. Examples of auto-update scripts for Windows, OS X, Linux, EC 2, OPENWRT are available on our website.

    Managed. Provides the ability to conveniently edit the contents of zones, import them from the BIND server zone file format, or by using AXFR request to the specified master server.

    We try to quickly respond to technical support and feedback'i calls from our users, we take into account their suggestions and wishes regarding the improvement and addition of our services, so that our service becomes even more convenient and easy to use.
    At the moment, all the services of the site are completely free. After registration, you will receive a license to manage a certain number of domains. And by subscribing to our page on Facebook - you will get a “bun”.

    We thank you for your attention. Comments are welcome.
