Buying a domain without checking its history is how investors inherit someone else's problems: a burned reputation from past spam, an active configuration you didn't expect, or an age that undercuts the seller's story. A few quick lookups before you wire money reveal what a listing page won't tell you.
This workflow helps buyers vet a domain: inspect current DNS records, confirm age, trace where it redirects today, and brainstorm alternatives if the target is taken or overpriced.
