Skill: DevSecOps Free DNS

Goal

Identify free DNS management, CDN, SSL/TLS, and DDoS protection services.

Use This Skill When

Setting up domain infrastructure at zero cost
Adding CDN/SSL without infrastructure
Implementing DDoS protection for free

Do Not Use This Skill When

Enterprise DNS with SLA requirements
Complex DNS routing rules

Inputs

Domain count
Traffic volume
SSL certificate needs
DDoS protection requirements
