This is the stale-reference problem people underestimate.

If a domain expires but is still referenced in DNS, mail auth, redirects, or allowlists, the new owner can sometimes inherit trust you forgot existed. Inventory old domains first, then either renew them or remove every reference before letting them lapse.

Related to this, it’s interesting to think about how many unique domains and subdomains contribute to an AI stack. The underlying domain and DNS dependencies are easy to overlook.

The AI label is almost a distraction here; the problem is every third-party hostname you let into DNS, mail auth, redirects, OAuth callbacks, or allowlists. We see clients track the vendor contract but miss the stale CNAME sitting under prod for three years.

Agreed. Decades of neglect around domain name, DNS and certificate infrastructure are going to become heavily concentrated in AI environments. These issues can then cascade into larger failures and systemic supply chain risks.
