DNS record types
A and AAAA records map a name to IPv4 and IPv6 addresses. CNAME creates an alias to another name. MX lists the mail servers for a domain, in priority order. NS shows the authoritative name servers, SOA holds zone metadata, TXT carries free-form text such as SPF, DKIM and site-verification tokens, and CAA restricts which certificate authorities may issue TLS certificates.
Checking DNS propagation
We query public resolvers (Cloudflare and Google), so results reflect what most of the internet sees. After changing a record, old values can persist until the previous TTL expires.
Preguntas frecuentes
Why do I get no results?
The domain may not exist, may not have that record type, or its name servers may be unreachable.
Can I check SPF and DMARC?
Yes. SPF is a TXT record on the domain itself; DMARC is a TXT record on _dmarc.yourdomain.com.
