Free WHOIS Lookup & DNS Records Checker
Check domain ownership, nameservers, website IP, DNS, MX, and SSL in seconds—powered by RDAP.
WhoisLogic is a free WHOIS lookup and DNS checker for developers, agencies, domain owners, and security teams. Enter a domain to see its registration status, registrar, creation and expiry dates, authoritative nameservers, website IP addresses, MX and TXT records, and SSL certificate status in one report.
Everything You Need in One Domain Lookup
Domain Registration & Ownership
See whether a name is registered, which registrar holds it, and the creation, updated, and expiry dates. Contact fields are often redacted; the public lifecycle facts still tell you who operates the name.
Nameservers & DNS Records
Authoritative nameservers show who controls DNS. The same report includes apex A/AAAA, MX, and TXT records so you can confirm delegation, hosting, and mail without a second tool.
Website IP & SSL Status
Apex A and AAAA records are the website IP addresses browsers hit. SSL/TLS status shows whether the current certificate is valid, who issued it, and when it expires.
Email Routing & Security
MX records describe inbound mail routing. SPF and DMARC usually live in TXT records; the lookup surfaces those strings so you can audit deliverability and spoofing controls.
Built for Developers, Agencies & Domain Teams
Troubleshoot Website Launches
Confirm nameservers, apex IPs, and TLS before a cutover. If DNS or the certificate is wrong, the report shows it before users do.
Audit Client Domains
Agencies can review registrar, expiry, mail routing, and SSL across client names in one workflow instead of stitching WHOIS and DNS consoles together.
Evaluate Domain Acquisitions
Use registration dates, nameservers, and live DNS as diligence signals. A no-record result is not a purchase guarantee—confirm availability at a registrar.
How the WHOIS Lookup Works
1. Enter a Domain
Type an apex domain such as example.com. WhoisLogic validates the name, then queries RDAP where the registry supports it, with DNS and TLS collected in parallel.
2. Review the Important Signals First
Registered names lead with website IP addresses, authoritative nameservers, and lifecycle dates. Empty no-record pages stay short so you are not wading through blank cards.
3. Copy, Export, or Investigate Further
Copy individual records, export JSON or CSV, or open MX, SSL, nameserver, DNS, and domain-age views when you need a deeper slice of the same snapshot.
WHOIS vs RDAP: What You’re Actually Seeing
People still search for WHOIS lookup because that is the familiar name for registration-data search. WhoisLogic uses RDAP where supported because it is the definitive structured gTLD registration-data source, then presents registrar, dates, statuses, and nameservers in plain language. DNS, website IP, MX, and SSL are resolved alongside RDAP so one report covers ownership and infrastructure.
Free WHOIS Lookup FAQs
- Is WhoisLogic's WHOIS lookup free?
- Yes. WhoisLogic is a free WHOIS lookup and DNS checker. You can look up registration status, nameservers, website IPs, MX records, and SSL without creating an account.
- What information does a WHOIS lookup show?
- A WHOIS lookup here shows registration status, registrar, creation and expiry dates, authoritative nameservers, website IP addresses, MX and TXT records, and SSL certificate status when those facts exist.
- Why is WHOIS contact information redacted?
- Most registries redact personal WHOIS contacts under GDPR and similar privacy rules. WhoisLogic still reports the public registration, DNS, and TLS facts that remain available.
- What is the difference between WHOIS and RDAP?
- WHOIS is the legacy text protocol people still search for. RDAP is the modern structured protocol ICANN uses for gTLD registration data. WhoisLogic uses RDAP where supported and presents the result in familiar WHOIS language.
- Can a WHOIS lookup confirm that a domain is available?
- No. A no-record result means the authoritative lookup found no active registration. Availability is not guaranteed until a registrar confirms it at checkout.
- Does WhoisLogic show nameservers and website IP addresses?
- Yes. Registered results put website IP addresses (apex A and AAAA records) and authoritative nameservers near the top of the report, separate from nameserver host IPs.
