Descriptions
DNS course for developers. I’ve had a lot of side projects over the years and I never figured out why my DNS records weren’t updating. Or how long to wait until they do it. Even worse, my emails were being bounced because I had configured SPF, DKIM, and DMARC incorrectly. I decided to explore DNS by creating Nslookup.io, a web interface for DNS. I read the RFC to implement my own DNS client and now I have my own DNS server. Nslookup has become popular enough to replace my income, so I’ve been working on it full-time since early 2022. Now that I’ve spent so much time learning DNS, I’m sharing everything I’ve learned in this comprehensive video course. . It will teach you to think about DNS from fundamental principles and protect you from the mistakes I made. After completing this course, you will be able to manage and debug DNS with confidence.
