Learn how DomainTools takes indicators from your network, including domains and IPs, and connects them with nearly every active domain on the internet. These connections help security professionals profile attackers, guide online fraud investigations, and map cyber activity to attacker infrastructure.
A Whois domain lookup allows you to trace the ownership and tenure of a domain name. Similar to how all houses are registered with a governing authority, all domain name registries maintain a record of information about every domain name purchased through them, along with who owns it, and the date till which it has been purchased.
The Whois database contains details such as the registration date of the domain name, when it expires, ownership and contact information, nameserver information of the domain, the registrar via which the domain was purchased, etc.
An IP is a unique address of a server on the internet. Similar to how a telephone number allows you to connect to a specific phone on the telecom network, similarly, an IP address allows your computer to connect to a specific server on the internet.
Domain names and IP numbers are the framework upon which the entire world wide web is built.
IP numbers are assigned to networking organisations with a record maintained by governing bodies for each IP number and the organisation to which it has been assigned. A whois IP lookup allows you track the above mentioned details for a domain.
Enter the domain or IP address for which you would like to conduct a Whois lookup in the search box above. We will query the appropriate database and provide a recent record.
If you have purchased a domain, the information stored with your Domain registrar is what is passed on to the Registry for the Whois database. Get in touch with your Registrar to make changes to the Whois contact information for each of your domains.
Some Registrars offer privacy protection services that allow their customers to mask their actual contact details in the Whois search result in order to prevent their private contact information falling into the hands of spammers and scammers. Get in touch with your Registrar to learn more about your options.
If the owner of a Domain name has used the privacy protection services of their Registrar, some details may be hidden within the Whois lookup results. Additionally, some Registries proactively conceal some information in order to comply with local data privacy protection laws.
According to the rules established by ICANN, Registrars are expected to maintain the accuracy of the domain name owner's contact details in the Whois database. Most Registrars use the details provided by the buyer at the time the Domain was registered.
In case your information does not match the Whois results, you can change this information by getting in touch with your Registrar who will be able to assist you in updating your information. Once this information is updated, the Whois record will also update accordingly. On an average, it can take 24-24 hours for this change to reflect in the Whois database.
You can use the Whois lookup service to find the registration status of a domain name. If the domain has not been registered and is available, you can use Whois.com to register the domain name.
Alternatively, if the domain name has already been registered, you can either register similar available domain names that we suggest, or use the contact information provided in order to get in touch with the owner and respectfully negotiate a sale. Do note that unsolicited contact is forbidden using the information provided via the Whois lookup service.
You can check the availability of a domain name by searching for it on the Whois database. It will give you the status of whether the domain name that you are looking for is available or not. Doing this for multiple domain names over time can help you build a list of available domain names.
