Fast, free DNS and WHOIS lookups. See every record type, choose Cloudflare, Google, Quad9, or OpenDNS, and check domain registration details.
Nslookup: DNS Records is a fast, native DNS lookup tool for anyone setting up a website, configuring email, or troubleshooting networking issues.
Enter any domain name or IP address to instantly retrieve its DNS records, including A, AAAA, MX, TXT, CNAME, NS, SOA, and PTR. Whether you're pointing a domain to a new host, verifying SPF/DKIM/DMARC records for email deliverability, or confirming a DNS change has propagated, Nslookup gives you the answer in seconds — no terminal required.
The app automatically keeps a local history of the domains and IP addresses you've recently looked up, so you can jump back into a lookup without retyping it. This history stays on your device.
