Want to know who hosts the site? The Hosting Lookup turns these addresses into a company name, and tells you when Cloudflare is hiding the real host. Open Hosting Lookup →DNS is the internet's address book. When you type a domain, your device asks DNS where to go, and these records are the answers. One says which server shows the website, another says where email should be delivered, and others prove to services like Google or Microsoft that the owner really controls the domain.
Cached for is how long other computers may remember an answer before asking again. That's why a change to DNS can take minutes or hours to show up everywhere.
SPF and DMARC are the records that stop strangers from sending email that pretends to come from the domain. We spell out what each one allows, so you can tell whether a domain is protected.
Answers come from our server's view of DNS at the moment you look. Free use is limited to 100 lookups per day.
