There are also several sites, specialized in offering access to published data around the domain name ownership information. The process of performing DNS lookup involves accessing domain name in a particular field before clicking the search key. Search engine queries public records, which relate to the particular domain names then returns a confirmation that the desired domain name does exist. The search engine will also provide the user with a chance to redirect it to site, which provides any more details about the domain owner and the current date of expiry. At times it comes up with all the required information to facilitate or allow the user to contact a domain name owner to verify if it is possible to buy the domain name.
