DNS Lookup
Free online dns lookup — checking DNS propagation and mail/security records instantly.
Why query DNS records with ToolJiffy DNS Lookup?
The Domain Name System (DNS) translates human-readable domain names (e.g. example.com) into numerical IP addresses (192.0.2.1) and routes mail server traffic. Resolving DNS records is essential for verifying server migration, checking email security records (SPF, DKIM, DMARC), and troubleshooting propagation issues. ToolJiffy DNS Lookup queries public DNS records instantly in your browser.
- Multi-Record Type DNS Queries: Query A, AAAA, CNAME, MX, TXT (SPF/DMARC), NS, CAA, and SOA records.
- Encrypted DNS over HTTPS (DoH) Resolution: Queries secure Google and Cloudflare DoH resolution endpoints directly.
- Email Security Record Inspection: Inspects SPF rules, DMARC policies, and DKIM public keys for domain authentication.
- 100% On-Device Browser Security: Queries execute directly from browser memory without intermediate proxy logging.
Encrypted DNS over HTTPS (DoH) Query Engine
ToolJiffy's DNS lookup engine formats JSON-encoded DoH requests to Cloudflare (1.1.1.1) and Google Public DNS (8.8.8.8). It parses DNS resource records, TTL cache durations, and IP address mappings.
Whether verifying server IP migrations, inspecting mail exchange (MX) priority rankings, or checking SSL Certificate Authority (CAA) records, instant DNS resolution speeds up network diagnostics.
Client-side security for private domain queries
Querying DNS records for internal staging domains, mail servers, or client infrastructure should never log domain lookup history on remote servers.
ToolJiffy operates on a zero-cloud architecture. All DNS queries route directly from your browser to public DoH APIs. Your query data never leaves your device session.
Step-by-step guide to looking up DNS records
- Enter domain name: Type your target domain name (e.g.
example.com) into the lookup bar. - Select record type: Choose record type (
A,AAAA,MX,TXT,NS,CNAME). - View resolved records: Inspect IP addresses, TTL values, mail server priorities, and text records.
Frequently asked questions
How does the in-browser DNS Lookup Tool work?
ToolJiffy queries public DNS over HTTPS (DoH) APIs (Google Public DNS and Cloudflare 1.1.1.1) to resolve domain DNS records (A, AAAA, CNAME, MX, TXT, NS, CAA, SOA) in real time directly from your browser.
What DNS record types can be queried?
Query IPv4 addresses (`A`), IPv6 addresses (`AAAA`), Canonical Names (`CNAME`), Mail Exchange (`MX`), Text records (`TXT` for SPF/DKIM/DMARC), Name Servers (`NS`), Certification Authority Authorization (`CAA`), and Start of Authority (`SOA`).
What is DNS over HTTPS (DoH) and why is it secure?
DNS over HTTPS encrypts DNS queries inside HTTPS connections, preventing ISP DNS interception, eavesdropping, and spoofing.
Is my domain lookup history uploaded to any cloud server?
No, 100% private. DNS queries are sent directly from your browser to public DoH resolution endpoints. ToolJiffy logs zero query history.
How do I verify email security records (SPF, DKIM, DMARC) via TXT lookup?
Perform a `TXT` record query to inspect SPF policies (`v=spf1 ...`), DMARC records (`_dmarc.domain.com`), and DKIM public key records.
What is DNS propagation time when updating name servers or A records?
DNS record changes take anywhere from 5 minutes up to 48 hours to propagate globally, depending on the record`s Time-To-Live (TTL) cache value.
What does a CNAME record do?
A `CNAME` (Canonical Name) record aliases one domain name to another (e.g. `www.example.com` aliased to `example.com` or a CDN hostname).
Is ToolJiffy DNS Lookup free without limits?
Yes! ToolJiffy is 100% free with unlimited usages, zero account sign-ups, and zero watermarks.
