Helping customers understand their domain

There are plenty of WHOIS and DNS lookup tools out there. The problem was never access to data, it's that none of them help you explain what you're seeing to someone who doesn't do this every day.

A customer writes in because their domain isn't working. Support looks things up, finds the issue, and then has to explain it, usually by pointing them to a third-party tool they've never used and telling them which field to look at. Every extra step is a chance for the conversation to stall.

whois.vercel.support puts registration, DNS, and SSL data on one page, in plain language. But the real feature is this: a support engineer can attach a note to any specific field and share a link. The customer opens it and sees their domain's data with the explanation right next to the thing it's about. No "go to this site and find the third A record." Just one link, the data, and the context.

A few things that make it useful beyond a basic lookup:

• Vercel-aware DNS records pointing to Vercel are labeled. Legacy settings are flagged with guidance to update. Verification records are shown separately.
• Propagation view queries five resolvers and shows whether they agree, so "wait for propagation" becomes something you can actually see.
• Snapshots freeze a lookup at a point in time so both sides of a support conversation are looking at the same thing.
• Plain language every field has context. Status codes are explained. Expiration dates are color-coded.

Anyone can look up a domain, customers see the same data support sees. The annotation features require a Vercel login to create, but anyone can view them. Same tool, same view, shared understanding.
