Managing DNS in Cloudflare for UnderHost hosting
Move your domain's DNS to Cloudflare, configure A, CNAME, and MX records for your UnderHost hosting, and understand the proxy (orange cloud) vs DNS-only modes.

When you use Cloudflare, your domain's nameservers point to Cloudflare rather than UnderHost. Cloudflare then hosts your DNS zone and proxies traffic through its network. This is what enables CDN, DDoS protection, and firewall features.
Move DNS to Cloudflare
- Create a Cloudflare account and add your domain
- Cloudflare scans and imports existing DNS records
- Review and confirm the imported records are correct
- Update your domain's nameservers at your registrar to the Cloudflare nameservers shown (e.g.,
anna.ns.cloudflare.com) - Wait for nameserver propagation (up to 24 hours)
Configure records for UnderHost
After moving to Cloudflare DNS, your records should look like this (replace the IP with your server's IP from CustomerPanel):
| Type | Name | Value | Proxy |
|---|---|---|---|
| A | @ | Your server IP | Proxied (orange cloud) |
| A | www | Your server IP | Proxied (orange cloud) |
| MX | @ | mail.yourdomain.com (or your mail server) | DNS only (grey cloud) |
| A | Your server IP | DNS only-must NOT be proxied for email | |
| TXT | @ | SPF record | DNS only |
Proxy vs DNS-only
Each DNS record in Cloudflare can be either Proxied (orange cloud) or DNS only (grey cloud):
| Proxied (orange cloud) | DNS only (grey cloud) | |
|---|---|---|
| Traffic routing | Through Cloudflare network | Direct to your server |
| Server IP hidden | Yes-visitors see Cloudflare IPs | No-real IP is visible |
| CDN / caching | Active | Not active |
| DDoS protection | Active | Not active |
| Use for | Web (A, CNAME for HTTP/HTTPS) | Email, FTP, SSH, non-HTTP services |
Email records with Cloudflare
Email traffic never goes through Cloudflare's proxy-MX records always resolve directly. However, you must ensure the mail A record (used by mail.yourdomain.com) is set to DNS only (grey cloud). If it's proxied, email clients connecting to port 25/465/587 will fail because Cloudflare only proxies web ports (80, 443).
