"Current DNS" displays the registration information for the current domain. It is possible to infer to some extent whether or not some kind of attack is being carried out. If there are other domains registered with this email address, the list can be displayed. Most of them are diagnosed as malware download sites, and they are still displayed as active, so you can see that they are extremely dangerous sites.Īlso, the WHOIS information shows the email address of the domain registrant, so click on it.
