Hy when i open "Show IP Address Usage" page some domain registerd to duplicate ip, then the result duplicated ip show default cpanel page (server ip:80)
Thanks for that confirmation. Is there a NAT configuration on this server? Could you confirm there are no duplicate IP addresses that show up with this command?
I'm not seeing anything out of the ordinary with the details you've provided. Could you create a ticket with our support team so we could investigate that?
