Vercel IP Ranges and ASN
We have not found an autonomous system registered to Vercel. Its sites answer from IP addresses that belong to other networks (cloud providers or CDNs), so IP ranges cannot identify Vercel; the checker relies on the signals below instead.
How to Check if a Website Is Hosted on Vercel
Enter the domain in the checker at the top of this page. It names Vercel when one or more of these signals match, and lists each one as evidence:
- The HTTP response carries an x-vercel-id header or a server header matching Vercel.
- The www record is a CNAME to vercel-dns.com, *.vercel.app.
- The domain uses Vercel nameservers (vercel-dns.com). This shows where DNS is managed, which is usually but not always the host.
