How to Do a Bulk Whois Search
When you register a domain name, you must provide contact information and something to identify you as the owner of the domain. This information is stored in a record called a Whois record. The information in a Whois record can be used by many different people and for various purposes. For example, hackers might use Whois records to determine a company's security measures and attack them. Businesses might also use Whois records to find out if their competitors have registered a similar domain and take action to prevent them from doing so.

In addition to the information required by the registry, you can also specify additional query flags when submitting a Whois query. These additional query flags allow you to modify the default behavior of a Whois query and return only specific information about a person or role, for example. You can also use the more and less specific query flags to request information about ranges of IP addresses rather than an exact match.

Telemarketers can scour Whois databases and develop lists to blanket target organizations with unsolicited phone calls and emails. Hackers can also use Whois data to break into a company's networks and attack their systems or steal confidential information.

It is important to understand that you must use the RIPE Whois Database in accordance with its terms of service, which include an agreement not to mine the database for contact information for non-agreed uses. Attempting to access the Whois database without such an agreement can result in your IP address being blocked from further queries to the RIPE Whois Database. This denial of access is based on the assumption that you are harvesting the information in the database to use it for commercial or other illicit activities.
