A single lookup on our service allows you to gather all the information available from a domain’s or an IP address’s corresponding WHOIS records. Find the name, email address, and physical location of a registrant as well as the domain’s creation, expiration, and last update dates and registrar to assess its current or future availability and age.
WHOIS Lookup contains the records of about 400 million currently active domains spanning more than 2,864 generic (gTLDs) and country-code top-level domains (ccTLDs).
WHOIS Lookup reports are parsed and normalized so professionals can easily access and make sense of the information they provide. Query results are available in seconds for faster decision-making.
WHOIS Lookup’s domain search query results come with custom URLs that users can readily share with relevant parties with just a few clicks.
We gather and refresh data in near-real-time so users can act on the most recent WHOIS insights on 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, including managed detection and response (MDR) firms quickly check for unknown domain names and IP addresses entering their clients’ networks. These may be used for spamming, 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. WHOIS History can also give them a historical perspective on domain ownership.
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 prepare for Uniform Domain-Name Dispute Resolution Policy (UDRP) cases.
Business professionals can use the information contained in WHOIS records to carry out background checks on new suppliers, customers, and partners before committing to contractual agreements or putting in large orders.
