Free tool · DNS lookup
What is the internet being toldabout your domain right now?
See the live DNS records for any domain: where the website points, where email goes, and how long answers are cached.
We log the domain you check to keep this tool working and see which tools are worth building. See our Privacy Policy.
What the record types mean
A and AAAA
Point the name at a server's address. A is the older IPv4 style and AAAA is the newer IPv6 style. This is where your website lives.
MX
Say which servers receive email for the domain. The lowest number is tried first.
NS and SOA
NS names the servers that hold the domain's records. SOA holds administrative details such as the primary server and a serial number.
TXT, CNAME, CAA and SRV
TXT holds notes such as email security and ownership checks. CNAME makes one name an alias of another. CAA limits who may issue certificates. SRV points a service to a host and port.
Frequently asked questions
What do A, MX and TXT records do?
An A record points a name at a server's IP address, which is how a browser finds your website. An MX record lists the servers that receive email for your domain. A TXT record holds free-form text, and is used for things like email security settings and proving you own the domain.
What is TTL?
TTL stands for time to live. It is the number of seconds a resolver may keep an answer before asking again. A short TTL such as 300 means changes spread quickly. A long TTL such as 86400 (one day) means fewer lookups, but old answers can linger after you make a change.
Why do different tools show different answers?
Resolvers keep answers in a cache, so one may still hold an old record while another already has the new one. Some DNS providers also answer differently depending on where you ask from. This tool asks Cloudflare's public resolver (1.1.1.1), so it shows what many people on the internet see. Wait for the TTL to pass and check again.
