A DNS record maps a name to a destination or publishes service instructions. Add records only at the authoritative DNS provider shown by the domain’s current nameservers.
Before you begin
Sign in through the official client area and keep account-specific values from your activation email available. Make a backup before changing production data or configuration.
Steps
- A and AAAA: A points a hostname to an IPv4 address; AAAA points it to IPv6. Remove stale values if the service does not use them.
- CNAME: CNAME makes one hostname an alias of another. It is commonly used for www, but generally cannot coexist with other records at the same name.
- MX: MX directs incoming email to mail servers. Lower preference numbers are tried first. Use the exact hosts supplied by the mail provider.
- TXT: TXT can publish SPF, DKIM, DMARC, and ownership-verification values. Preserve punctuation and split rules exactly as the provider specifies.
- CAA: CAA limits which certificate authorities may issue certificates for the domain. An incorrect CAA policy can prevent SSL issuance.
Important notes
- The host field may use @ for the root domain, depending on the DNS interface.
- A TTL controls cache lifetime; it does not guarantee that a change will appear instantly.
When to contact support
Contact support if the documented controls are unavailable, the service reports an account-level restriction, or the issue continues after these checks. Include the affected domain or service, the exact error, a timestamp with timezone, and the steps already tried. Never include passwords, one-time codes, private keys, or complete payment details.
