About

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. WHO IT'S FOR Developers and sysadmins setting up new sites or servers Anyone configuring email (SPF, DKIM, DMARC, MX records) IT and networking professionals troubleshooting DNS issues Domain owners verifying registrar or host changes

What's New in Nslookup

1.2

October 19, 2026

Email authentication, right in the app • New Email tab: check a domain's SPF, DKIM and DMARC records with a single tap. • SPF results show the full include tree, so you can see every host that is allowed to send on the domain's behalf. • DKIM takes an optional selector. Leave it blank and we probe the common ones for you. • Every email lookup produces findings, checks and tags, and can be exported as a PDF report. • Email lookups appear in your history. Tap a recent entry to rerun the exact same check. Settings and polish • Settings now lives in its own tab. The gear button is gone from the DNS, Whois and Email screens. • Fixed: the Appearance picker only applied the first change. Light, Dark and System now switch every time. • The clear button in lookup fields is bigger and easier to hit, and long text no longer runs underneath it.
