Six record types, one lookup
See exactly what your domain's DNS is currently publishing.
A & AAAA
The IPv4 and IPv6 addresses your domain currently points to.
MX & TXT
Mail servers handling your email, and text records like SPF, DKIM verification and site ownership proofs.
NS & CNAME
The nameservers authoritative for your domain, and any alias records pointing elsewhere.
DNS checker — common questions
Need a DNS record changed, not just looked up? Our engineers can make the change for you.
An A record maps a domain name to an IPv4 address — it's what tells browsers which server to connect to.
An MX record specifies which mail servers handle email for a domain, and in what priority order.
TXT records store arbitrary text data for a domain — commonly used for SPF, DKIM and DMARC email authentication, and domain ownership verification. See our email deliverability specialist service if you need these configured correctly.
That's usually normal. CNAME records are typically only used on subdomains, not the main domain, and AAAA (IPv6) records are optional — many servers only use IPv4.
