Blchecktool.com is used to check IP address range in DNS blacklist database (rbl) and find if any IP address is registered as a spam source in DNS blacklist database, because e-mails may be rejected and bounced by recipients if source email server IP address is registered as spam source.

E-mail servers administrators should be aware for this issue to avoid losing business emails for their organizations and also they should use anti-spam software to eliminate any spam e-mails from going out from their servers.

In case of accidently IP registered as spam source then e-mail administrators should remove IP address from DNS blacklist and eliminate the cause of this issue from their side.
