About Dean

Namibia-based DNS and hosting problem solver.

I’m Dean Theisinger. I focus on practical domain, DNS, mail and hosting troubleshooting for Namibian businesses, web designers, IT consultants and domain owners.

When a Namibian website disappears, mail stops arriving, or a .na / .com.na domain points to the wrong place, the real problem is often hidden between the registrar, nameservers, hosting panel, Cloudflare and mail DNS. That is the gap I help close.

My approach

I work at the operational layer where registrars, DNS providers, hosting panels, mail servers and Cloudflare meet. Instead of guessing, I inspect the public path and produce proof of the fault and the fix.

This site is deliberately specialised: Namibian domain reality, .na and .com.na handovers, DNS hosting, MX/SPF/DKIM/DMARC, Cloudflare proxy mistakes, propagation delays and safe hosting cutovers.

  • Clear root-cause diagnosis
  • Safe change planning before DNS changes
  • External verification from public resolvers and browsers
  • Plain-English explanations you can forward to a client or registrar
  • WhatsApp-first communication when something is urgent
