Training programme: DNS Administrator

Home > Products and services > Training > Training programme: DNS Administrator

For some years now, both public and private actors have been seeing certain Internet services become inaccessible on account of problems linked to their DNS hosting. These breakdowns have considerable consequences: clients unable to access their bank accounts, online stores inaccessible, public services closed, etc. The robustness of DNS services generally suggests that Internet services are functioning normally; so, without a suitable DNS administration, an organisation can become extremely vulnerable.

It is essential for any organisation to have skilled administration that allows it to maintain a comprehensive, high-quality DNS service, whether it is hosted in-house or entrusted to a hosting service provider.

Description and teaching objectives of the training programme

This training course will enable you to

  • Design a DNS architecture that provides quality resolution by implementing the best practices in the industry
  • Configure your DNS zone so as to prevent dysfunctions
  • Identify and resolve problems linked to DNS using benchmark tools and software
  • Assess the quality of your configuration using diagnostic examples of problematic configurations
  • Define operational standards (robustness, performance, etc.) to help you choose and evaluate your DNS host
