Features

Comprehensive Whois →

Get detailed Whois information for domains and IP addresses across more than 1,500 top-level domains (TLDs) and over 9,000 second-level domains (SLDs). Our robust and proprietary network infrastructure ensures faster and more reliable lookups, providing access to a broader range of domains, including those not typically supported by standard Whois clients.

With Deep Whois, you’ll see the final, consolidated Whois record instantly, as it automatically follows the chain of Whois servers to deliver the most accurate and complete data. This streamlined process saves you time and reduces clutter on your screen, giving you a clear and concise view of the information you need.

Whois History →

Go back in time with Historical Whois. View a domain's ownership history, registration changes, and key updates over time. Uncover valuable insights into how a domain has evolved, making it ideal for domain investors, cybersecurity professionals, and anyone needing a detailed domain history.

Notifications →

Stay informed with real-time alerts and never miss an important update. Track domain expiration dates and monitor any changes in Whois data, such as ownership, contact information, or name servers. Receive instant notifications to ensure you're always up to date on critical updates, helping you manage your domains effectively and avoid any unexpected issues.

Privacy Shield →

Protect your identity with Privacy Shield. This feature allows you to perform Whois lookups anonymously by hiding your IP address, ensuring your queries are private and secure. Whether you’re conducting sensitive research or simply value your privacy, Privacy Shield provides an extra layer of security, preventing your activities from being traced back to you.

Color Whois →

Enhance your Whois experience with customizable color themes, available on both iOS and Terminal clients for macOS, Linux and FreeBSD. Personalize your Whois lookup interface to match your style, making it easier to distinguish key information at a glance, whether you're on your mobile device or working from the command line.

Registration Data Access Protocol (RDAP) →

Seamlessly access detailed registration information for domains that have transitioned away from the traditional Whois protocol. RDAP provides a more modern and structured approach to retrieving domain data, offering enhanced security, standardized responses, and support for internationalized domain names (IDNs). With RDAP integration, you can effortlessly obtain comprehensive registration details, even for domains where standard Whois queries no longer apply.

Ethereum Name Service (ENS) →

Check ownership of .eth ENS domain registrations and Ethereum wallet addresses.

Monitor expiration of Ethereum domains with push notifications, timely alerts.

Take control of your digital identity with unparalleled ease and confidence.

Internationalized Domains (IDN)

Experience complete support for Internationalized Domain Names (IDN), enabling you to perform Whois lookups on domains that include non-Latin characters, such as those in Arabic, Chinese, Cyrillic, and more. With full IDN compatibility, Deep Whois allows you to effortlessly manage and investigate domains in various languages and scripts, breaking down language barriers and ensuring global accessibility.

Fast and Redundant Whois Infrastructure →

Ensure uninterrupted Whois lookups by seamlessly redirecting queries through our reliable TLD registry service whenever the centralized top-level domain registry (used by the stock whois) is unavailable.
