DNS lookup

Also check this domain: Who hosts this website?SSL checker Is it down? + speed WHOIS lookup

Look up every public DNS record for a domain in one go: A and AAAA (the server addresses), CNAME aliases, MX mail servers, NS nameservers, TXT records (SPF, DKIM, DMARC and verification codes), SOA and CAA, each with its TTL.

What each record means

A / AAAA: the IPv4 / IPv6 address the domain points to. Change these to move a site to a new host.
CNAME: an alias pointing one name to another, common for www and services like Shopify.
MX, where the domain's email is delivered, in priority order.
NS: the nameservers responsible for the domain's DNS.
TXT: free-form text: SPF and DMARC email policies, DKIM keys and site verification codes.
SOA: the zone's primary nameserver and serial number.
CAA, which certificate authorities may issue SSL certificates for the domain.

TTL and propagation

The TTL (time to live) is how long resolvers cache a record. When you're about to switch hosts, lower the TTL to a few minutes a day in advance so the change spreads quickly.

Frequently asked questions

Why don't I see my new DNS records yet?

Resolvers cache records for their TTL. Our lookup uses a public resolver, so a recent change may take up to the old TTL to appear.

How do I check if my email DNS is set up?

Look for MX records pointing to your email provider and TXT records for SPF (v=spf1…) and DMARC (on _dmarc.yourdomain).

What's the difference between NS and A records?

NS records say which servers answer DNS questions for the domain; A records are the answers that point to your website's server.
