Show HN: Are premium domains ever worth it? A technical deep dive

Hi HN, I recently bought a premium domain while working on a small product and realized there’s a lot of confusion around what “premium” actually means at the registry and infrastructure level.

I wrote a technical breakdown covering things like registry pricing vs aftermarket, renewal structures, DNS (no magic there), email deliverability, and when paying more actually removes real product friction.

This isn’t about branding or SEO tricks. It’s more about treating domains as long-term infrastructure decisions.

Would genuinely love to hear how others here think about premium domains, especially around renewals and lock-in.
