DNS Lookup
Query DNS records for any domain. View A, AAAA, MX, NS, TXT, CNAME, and SOA records.
Read how to read these DNS records. This query uses the site’s server resolver and shows record values, not your device’s DNS path or ordinary record TTLs.
Learn why DNS answers can take time to change. Opening this tool from another network does not reliably compare the resolvers used by those devices.
If records look correct, troubleshoot a site that will not load before changing more settings.
This tool looks up names. For the reverse direction — which hostname an IP address claims — read reverse DNS (PTR) explained. To keep your own lookups private from the network you are on, see DNS over HTTPS.
An A or AAAA answer is an address, not a provider name. Find the ISP for that IP address, or find out your own ISP from the connection you are using. DNS queries are one thing a provider may observe — what your ISP can see covers HTTPS, DNS, and VPN separately.
If that address is shared by many customers, the network name still does not identify one home. Read what CGNAT means for a shared public IP, and how to tell if you are behind CGNAT.
