Get key data points for domains, including Registrant name, organization, e-mail address, registration address, registrar information, creation date, expiration date, updated date, domain availability, domain age, and even more.
WHOIS Lookup is powered by about 400 million currently active WHOIS records for more than 2,864 generic top-level domains (gTLDs) and country-code top-level domains (ccTLDs).
WHOIS Lookup reports are parsed and normalized such that professionals can easily access and make sense of the information. Query results are available in seconds for faster decision-making.
WHOIS Lookup’s domain search query results come in preview HTML mode as well as JSON and XML formats. Users can also share hosted reports with relevant parties in a few clicks.
We gather and refresh our data in near-real-time so that users can act on the most recent WHOIS insights regarding domain names and IP addresses of interest.
Threat detection specialists, digital forensics & incident response (DFIR) teams, or even non-technical users can use WHOIS lookups to find out more about domain names, IPs, and email addresses. Suspicious hosts and their WHOIS records can be investigated further to reduce the risk of malware-driven and phishing-led attacks.
WHOIS Lookup lets external cybersecurity consultants and managed security firms quickly check for unknown domain names and IP addresses entering their clients’ networks and that may be used for spam, spoofing, and other domain-related attacks. Service providers can also use the tool to update their blocklists with reliable WHOIS data.
Law enforcement agencies can rely on WHOIS Lookup to quickly check if a particular domain name’s registration details share patterns with known or emerging online criminal networks.
Domain investors and brokers can use WHOIS Lookup to get an overview of a web domain’s availability and current ownership information.
Domain brokers and registrars can double-check a domain name’s latest details and verify ownership before finalizing a sale and proceeding with the domain transfer.
Conducting regular WHOIS domain and website searches can give business professionals an edge as new web name registrations may be indicative of competitors’ future product launches or international expansions.
Users can check the credibility of a person’s email address for telltale signs of spoofing and business email compromise (BEC) fraud, such as very recent registration, too frequent updates, or other anomalies.
Users can benefit from WHOIS Lookup’s outputs to investigate possible instances of brandjacking and typosquatting as well as to prepare for Uniform Domain-Name Dispute Resolution Policy (UDRP) cases.
Business professionals can use the information contained in WHOIS records to carry a background check on new suppliers, customers, and partners before committing to contractual agreements or large orders.
