I bought my 2nd domain only a few days ago. I've been using it heavily to learn all about DNS. I must say I've greatly demystified how they work. I've even gone deeper and understood how the Nginx Web Server uses domains and subdomains to act as a reverse proxy. A CNAME (Masking) TXT MX Masking 301 302 HTTP to HTTPS redirection TTL SSH SSL 80 22 443 Path Forwarding Dynamic and Static IP Dynamic DNS Port Forwarding Azure VMs Azure App Services Azure Functions I understand them better now.
Happy the man,and happy he alone, He,who can call today his own; He who,secure within,can say, Tomorrow do thy worst,for I have lived today.
