Documented labs, troubleshooting guides, and IT career learnings.
What email authentication actually is, why recruiters' spam filters demand it, and how I configured a full enterprise-grade stack on a $10 domain — with every DNS record explained.
What a domain really is in the DNS hierarchy, why renewal pricing matters more than promo pricing, and how to set one up with Cloudflare from scratch.
