FREE DNS TOOL

Domain Check

Read MX, TXT, SPF, NS, SOA and address records, or reverse DNS for a public IP. No account required. No email is sent. The DNS lookup does not connect to your mail server. Optional MX tests check SMTP connectivity and TLS separately.

Do not enter a URL or email address. Queries use our own local recursive DNS resolver and may reflect cached DNS. NS records identify the domain’s authoritative servers; they are not your device’s DNS settings.

What this check does not prove

These are DNS observations, not a delivery, security or uptime certification. The tool displays public SPF text but does not validate message authentication, recipients, account ownership, DKIM or SMTP acceptance. It does not change DNS or your service settings.
