# `disposable_email_from_datacenter_ip`: a disposable address arriving from a datacenter

The email is on a disposable-provider list and the request came from hosting rather than from a consumer network.

- Appears in: `flag`
- Billing: Free. The consistency analysis is arithmetic over answers already paid for and never costs a credit of its own.

Each half is already published by its own product: `disposable` on the email answer, `is_datacenter` on the IP answer. The flag only names that both are true at once.

Automation and server-side integrations legitimately run from datacenters, so this pairing is weaker when your own backend forwards the call than when a browser does.

**What to do.** Useful at signup, where a real person is expected to arrive from a consumer network with an address they can receive mail at.
