GitHub Pages Nameservers
GitHub Pages does not ask customers to move their nameservers. Your domain stays with its current DNS provider, and you point it at GitHub Pages with the A, AAAA or CNAME record shown in your GitHub Pages dashboard (CNAME targets look like *.github.io). Verify the record afterwards with the DNS lookup.

GitHub Pages IP Ranges and ASN
We have not found an autonomous system registered to GitHub Pages. Its sites answer from IP addresses that belong to other networks (cloud providers or CDNs), so IP ranges cannot identify GitHub Pages; the checker relies on the signals below instead.
How to Check if a Website Is Hosted on GitHub Pages
Enter the domain in the checker at the top of this page. It names GitHub Pages when one or more of these signals match, and lists each one as evidence:
- The HTTP response carries an x-github-request-id header or a server header matching GitHub Pages.
- The www record is a CNAME to *.github.io.
