🔎 WHOIS Domain Lookup
Check domain registration details — registrar, dates, name servers and domain age via RDAP.
FETCHING WHOIS DATA...
What is WHOIS Lookup?
WHOIS is an internet protocol used to query registration databases for domain names, IP addresses, and autonomous systems. When you register a domain, your registrar submits your details to the authoritative registry for that TLD. WHOIS lookup retrieves this publicly available registration information including registrar name, registration and expiry dates, name servers, and domain age.
ToolsNovaHub uses RDAP (Registration Data Access Protocol), the modern JSON-based successor to legacy WHOIS. RDAP provides structured, standardised responses over HTTPS with better international character support and consistent field names. It is now used by all major registries including Verisign for .com and .net domains.
WHOIS data is used by security researchers to identify domain owners behind phishing sites, businesses to check domain history before purchase, administrators to verify name server configuration, and legal teams for intellectual property matters.
How to Use It?
Enter a domain name without http:// or www and click Lookup →. The tool queries the authoritative RDAP endpoint directly and shows registrar, creation and expiry dates, domain age, name servers, and country. The Raw RDAP Data section shows the complete structured JSON response. Use ❏ Copy Raw to copy it.
Example: A buyer is considering purchasing a domain that's "for sale" via a third party. A WHOIS Lookup shows the domain was registered only 3 months ago and expires in 9 months — a red flag suggesting it isn't an aged, established domain as the seller claimed.
🔄 The Domain Lifecycle
Every domain name moves through a predictable lifecycle from registration to potential expiry. Understanding this cycle helps you interpret WHOIS dates correctly and avoid accidentally losing a domain:
| Stage | Typical Duration | What Happens |
|---|---|---|
| Active / Registered | 1–10 years (renewable) | Domain is live and fully under owner's control |
| Expired (grace period) | 0–45 days after expiry | Owner can still renew at normal price; site may be suspended |
| Redemption Period | ~30 days | Domain locked; owner can reclaim only by paying a steep redemption fee |
| Pending Delete | ~5 days | Domain is queued for release; cannot be renewed by anyone |
| Available / Re-registration | — | Domain released back to the public — anyone can register it |
This tool's Domain Timeline visualises where a domain currently sits within its CURRENT registration period (created → today → expires) — useful for spotting domains nearing renewal.
🔐 Domain Status Codes Explained
The "Status" field uses standardised EPP (Extensible Provisioning Protocol) codes. These often LOOK alarming but are usually completely normal:
⏳ The Redemption Period — Why It Matters
When a domain expires and isn't renewed within its initial grace period (typically 0–45 days, varies by registrar), it enters the Redemption Grace Period (RGP) — roughly 30 days during which:
- The domain is taken OFFLINE (website and email stop working)
- DNS records may be removed by the registry
- The ORIGINAL owner can still recover it, but typically must pay a substantial redemption fee on top of the normal renewal price — often 10–20× the standard renewal cost
- No one else can register the domain during this period
After redemption period ends, the domain enters pendingDelete (about 5 days) and is then released for anyone to register — including domain-squatters who actively monitor expiring domains. Lesson: always set renewal reminders well before the "Expires On" date shown by this tool — don't rely on the grace/redemption periods as a safety net.
⚖️ Registrar vs Registry — What's the Difference?
| Registrar | Registry | |
|---|---|---|
| What it is | The company YOU buy/manage your domain through | The organisation that operates the entire TLD (e.g. all .com domains) |
| Examples | GoDaddy, Namecheap, Google Domains, BigRock | Verisign (.com/.net), PIR (.org), NIXI (.in) |
| Who you contact for renewal/transfer | ✅ Registrar | ❌ Not directly — registries don't deal with end customers |
| Who sets the EPP status codes | Most client* statuses (clientTransferProhibited, etc.) | Most server* statuses (serverHold, pendingDelete) and overall TLD policy |
| Shown in this tool as | "Registrar Information" card | "RDAP Source" field (shows which registry's RDAP server responded) |
Think of it like renting an apartment: the registrar is your landlord (who you pay rent to and call for issues), while the registry is the city government that maintains the overall zoning rules for the whole neighbourhood (the TLD).

| Tool | Shows | Best For |
|---|---|---|
| WHOIS/RDAP (this tool) | Registrar, dates, registration status, nameservers | "Who owns/controls this domain and until when?" |
| DNS Lookup | Live A/MX/TXT/NS records | "Where does this domain actually point to right now?" |
| IP Lookup | Hosting location of the IP a domain resolves to | "Where is this server physically/network-wise?" |
