Domain Name System Course

GoLogica provides DNS – Domain Name Server Online Training, designed for individuals involved in the development, testing, and verification of the DNS protocol. It provides a deep understanding of the DNS protocol's architecture, components, and operational mechanisms. Upon successful completion of the course and exam, you will be certified as a DNS Online Training Professional.

The course covers topics like domain name hierarchy, DNS servers, and domain name resolution. It also addresses common DNS issues and troubleshooting techniques. Practical exercises and real-world scenarios reinforce theoretical knowledge, allowing learners to apply concepts to their work environment. This course is an invaluable resource for those looking to deepen their DNS expertise.

DNS is a fundamental internet service that allows computer-to-computer communication by converting human-readable domain names into numeric IP addresses. It works by using an ordered server structure, where authoritative name servers store DNS records and root servers handle requests for top-level domain (TLD) servers.

The process begins when a user types a domain name. A DNS resolver receives the query and responds with the IP address that corresponds to it. In addition, DNS has cache techniques to lower latency and speed up resolution, as well as security measures like DNSSEC to ensure data integrity.
