PingKit sends DNS queries directly from your iPhone and displays the raw results. Pick a domain, choose a record type, and optionally select a specific DNS server to query against. Results include the full record data, TTL values, and response time. It's the equivalent of running dig or nslookup from a terminal, but on your phone.
Query A, AAAA, MX, TXT, CNAME, NS, and SOA records. Whether you're checking where a domain points, verifying mail configuration, or inspecting SPF records, every record type is supported.
Query against specific DNS servers like Google (8.8.8.8), Cloudflare (1.1.1.1), or your ISP's resolvers. Compare results across servers to verify propagation status after DNS changes.
Results appear in milliseconds with full record details and TTL values. No waiting for web-based tools to load. Run lookups on the go, even from your phone's cellular connection.
After updating DNS records, query multiple servers to see which ones have picked up the change. Confirm propagation is complete before switching services or decommissioning old infrastructure.
You just updated your domain's A record to point to a new server. But is the change live? DNS propagation can take minutes or hours depending on TTL values and caching. Run a lookup against authoritative nameservers first to confirm the change was accepted, then check public resolvers like Google and Cloudflare to track propagation progress.
Email delivery problems are often DNS problems. If mail isn't reaching your domain, look up the MX records to verify they point to the right mail servers with the correct priority values. A missing or misconfigured MX record is one of the most common causes of email routing failures, and it takes seconds to check with PingKit.
Email authentication relies on TXT records in DNS. Your SPF record defines which servers can send mail for your domain. DKIM records contain the public keys for signature verification. If these records are wrong, your outgoing mail lands in spam folders or gets rejected entirely. Look up your domain's TXT records to verify the configuration matches your email provider's requirements.
When a website isn't loading, DNS is the first thing to check. Is the domain resolving at all? Is it pointing to the right IP? Is a CNAME chain broken? A quick DNS lookup reveals the answer immediately. Combined with PingKit's ping tool, you can determine in seconds whether a problem is DNS, server, or network related.
Web developers, sysadmins, and DevOps engineers don't always have a laptop handy when DNS issues arise. PingKit puts a full DNS lookup tool in your pocket so you can diagnose and verify DNS configurations from anywhere. Combined with SSL Inspector for certificate verification, port scanner for service availability, and WHOIS for domain ownership details, PingKit covers the complete domain troubleshooting workflow.
