I was trying to delete ns1.something.com and ns2.somthing.com records from the DNS functions using cPanel.. however the records has been successfully erased.. but when I go back to Nameserver IPs under newtworking setup.. I still can see them there.. is there any specific file I can access on my vps so I can remove them?
In CPanel? I think DNS related operation need sometime to go into effect. Just wait and try logout your CPanel again.
