I have a rogue nameserver listed on my WHM for some reason. I found it when I went to Manage Nameserver IPs . When I tried to delete it it gave me the error: Sorry, the nameserver ip x.x.x.x cannot be removing since it is still registered with an ICANN register.. So it seems that someone is sitting on one of my IP addresses or they used to have it and they didn't delete the nameserver from their registrar. In any case. How can I get rid of this?
