RDAP Domain Lookup

What is RDAP Domain Lookup?

RDAP (Registration Data Access Protocol) Domain Lookup is a next-generation domain query tool that replaces the old WHOIS protocol, offering much more secure, standardized, and machine-readable (JSON) data. Using IANA's (Internet Assigned Numbers Authority) direct bootstrap infrastructure, it provides instant and real data on who owns any domain name (e.g., .com, .net, .org, etc.), when it was registered, when it expires, and registrar information.

WHOIS vs RDAP: What are the Differences?

• Standard Format: While the WHOIS protocol returns a text block, its format varies from company to company. RDAP returns standardized JSON.
• Security and Privacy: RDAP is designed in accordance with GDPR processes and hides unnecessary personal data, preventing unauthorized data scraping.
• Internationalized Domain Name (IDN) Support: RDAP has much higher accuracy in domain searches containing international characters.
• Authoritative Server Redirection: When searching, it first queries the central IANA, which redirects you to the authoritative company (e.g., GoDaddy, Namecheap) to guarantee you get the most up-to-date information.

Importance of Domain History and Age for SEO

In Search Engine Optimization (SEO), "Domain Age" is a factor that determines the authority and trust (TrustRank) of your site. Newly registered domains generally enter a Sandbox period and struggle to rank high immediately. On the other hand, running an RDAP and Wayback archive check is a vital security step when buying dropped expired domains that might have been involved in spam or blacklisted in the past.

How to Use?

Type the URL you want to query (e.g., seoaraci.com or example.co.uk) and search. The tool will display the domain's Creation Date, Expiration Date, Registrar, and DNS Name servers.

Frequently Asked Questions (FAQ)

Question: I did an RDAP query, but the owner's personal name/phone isn't listed, why?
Answer: Due to GDPR and privacy protection (WHOIS Protection), ICANN now prevents the public sharing of individual personal contact information by default.

Question: Is this data definitive for buying an expiring domain?
Answer: Yes, the Expiry Date is the official end date of the domain. However, companies usually offer a "Grace Period," meaning the domain cannot be purchased by someone else the exact day it drops.
