Documented adding a www DNS record in Cloudflare (CNAME to apex or Pages). | Dev Logs

Date: 2026-01-11 11:09 Summary: Documented adding a www DNS record in Cloudflare (CNAME to apex or Pages).

[question] how cloudfare setting: add www domain dns setting

[try to solve] Goal: make www.example.com resolve.

A (common/recommended): CNAME www → apex

1. Cloudflare Dashboard → site → DNS → Records → Add record.
2. Fields:

• Type: CNAME
• Name: www
• Target: example.com (or @ if the UI allows)
• Proxy status: Proxied (orange cloud, usually recommended)
• TTL: Auto

3. Save; wait a few minutes for propagation.

B (Cloudflare Pages): CNAME www → xxx.pages.dev

• Type: CNAME
• Name: www
• Target: <your-project>.pages.dev
• Proxy: Proxied/Auto per Pages guidance Also add www.example.com as a Custom Domain on the Pages project (Cloudflare configures/validates).

Common issues

• DNS only but still unreachable: check SSL/TLS and whether the origin accepts that Host.
• If you already 301 www → apex, still keep the www DNS record so clients can resolve before the redirect.
