There are many reasons you might want to do a domain name lookup. These may contain the following –
1. To learn if you want to purchase it, get the past information of it using whois api if your name is chosen. You want a unique name, and may have an excellent idea for a website. (In this situation, simply type the domain name onto the address area of a browser. You are going to either get a message that the website cannot be located, which suggests it’s not filed yet; or you’ll be taken to a web site which uses the domain name already.)
2. To see which company or person possesses a particular domain.
3. So you could send an offer to purchase it to get the contact details for the owner of a domain.
4. To use the lookup info to contact specialized contact or the domain owner to whine about something incorrect or offensive on the website, or, for example, because the website has pictures or content which were shot from a website you possess yourself, breaking copyright. (In this situation, the nameserver info may give a hint about the name of the hosting service used by the domain owner, whom you could also complain too.)
5. To contact the owners of a domain who’ve infringed on a logo that you control or possess.
So, how can you do a domain name lookup anyhow? Just go to whois api and use their search boxes. That is free. Minimal enrollment data for present domain names that you will have the ability to see following a lookup contains the nameservers, and the registrant’s name, which the domain is registered through. According to the policies and set up of the registrar, you may even have the ability to get a physical address, a contact email address and a phone number for the technical contact and for the registrant.
