1. What is WHOIS?
WHOIS is a public query protocol and database that stores information about domain name registrants worldwide. When you register a domain, your registrar submits your contact details to the WHOIS database as required by ICANN (Internet Corporation for Assigned Names and Numbers).
Anyone can look up WHOIS data using free tools such as:
- who.is — popular WHOIS lookup tool
- whois.domaintools.com — comprehensive domain intelligence
- rdap.org — the modern replacement protocol for WHOIS
- AsiaGB WHOIS Tool — search at asiagb.com/whois.html
2. What is WHOIS Privacy Protection?
WHOIS Privacy Protection (also called Domain Privacy or Private Registration) is a service that hides your personal information from the public WHOIS database.
Instead of displaying your real name, address, phone number, and email, the system shows proxy contact information from the registrar or a privacy service provider, which acts as a shield between you and the outside world.
3. What Data Does WHOIS Expose?
Typically, WHOIS reveals information for the Registrant, Admin Contact, and Technical Contact, which includes:
| Data Type | Example | Risk if Exposed |
|---|---|---|
| Full Name | John Smith | Identity theft, Social engineering |
| Physical Address | 123 Main St, Bangkok | Physical harassment, Junk mail |
| Phone Number | +66 81 234 5678 | Spam calls, Phishing |
| Email Address | [email protected] | Email spam, Phishing campaigns |
| Organization Name | My Company Ltd. | Targeted attacks, Competitor intelligence |
| Domain Expiry Date | 2027-11-06 | Domain hijacking attempts |
4. Why Do You Need WHOIS Privacy?
Exposing your personal data in WHOIS creates several real risks:
Stop Spam and Unwanted Calls
Spam bots automatically harvest emails and phone numbers from WHOIS databases. With WHOIS Privacy enabled, your real contact details are no longer visible, dramatically reducing spam from this source.
Reduce Phishing and Social Engineering Risk
Attackers can use WHOIS data for targeted phishing — for example, sending fake emails claiming to be your registrar asking you to renew your domain through a fraudulent link.
Protect Personal Privacy
For bloggers, writers, or individuals running personal websites, keeping your home address out of a public database is an important safety measure.
Prevent Domain Squatting
Competitors can check your domain's expiry date via WHOIS and attempt to register it the moment it expires. WHOIS Privacy partially conceals this information.
5. How Does WHOIS Privacy Work?
When WHOIS Privacy is activated, the system replaces your real information with proxy contact details:
| Without WHOIS Privacy | With WHOIS Privacy |
|---|---|
| Name: John Smith | Name: Privacy Proxy Service |
| Email: [email protected] | Email: [email protected] |
| Phone: +66812345678 | Phone: +1-480-555-0000 |
| Address: 123 Sukhumvit, Bangkok | Address: Registrar HQ Address |
When someone sends an email to the proxy address shown in WHOIS, many registrars will forward it to your real email (after spam filtering), so you can still receive legitimate contact attempts without exposing your real address.
6. Pros and Cons of WHOIS Privacy
| Pros | Cons |
|---|---|
| ✅ Prevents email spam and unwanted calls | ❌ Additional cost (usually $5-15/year) |
| ✅ Reduces phishing risk | ❌ Not supported by all TLDs |
| ✅ Protects personal privacy | ❌ Legitimate contacts may have difficulty reaching you |
| ✅ Deters domain squatting | ❌ Doesn't hide from legal processes |
| ✅ Zero impact on website functionality | ❌ Some proxy emails may filter valid messages |
| ✅ Easy to toggle on/off anytime | ❌ Some businesses require public contact info |
7. Which TLDs Support WHOIS Privacy?
Not every TLD allows WHOIS data masking — it depends on the registry's policies:
| TLD | WHOIS Privacy Support | Notes |
|---|---|---|
| .com / .net | Supported | GDPR-compliant, some registrars offer free privacy |
| .org | Supported | PIR (Public Interest Registry) allows it |
| .info / .biz | Supported | Supported per ICANN standards |
| .io / .co / .me | Supported | Most popular ccTLDs support it |
| .th / .co.th | Not Supported | THNIC requires real contact data display |
| .ac.th / .go.th | Not Supported | Academic/government Thai domains |
| .de (Germany) | Partial | GDPR mandates some data masking automatically |
| .uk | Supported | Nominet allows Privacy Proxy services |

9. WHOIS Privacy and GDPR
Since GDPR took effect in 2018 in the European Union, the WHOIS landscape has changed significantly:
- ICANN policy adjustment — Registrars in Europe and many globally now automatically mask registrant data
- RDAP replaces WHOIS — The new RDAP (Registration Data Access Protocol) standard offers better access control
- Tiered Access — ICANN is developing a system granting only authorized parties (law enforcement, IP rights holders) access to real data
- Benefit for Thai users — Thailand's PDPA (Personal Data Protection Act) follows a similar direction, though enforcement differs
