When a reseller receives a dedicated server he gets only one IP address. If it is allowed by the plan he signed up with, he can always send requests for additional IPs from your cp. To send a request for an extra range of IPs reseller has to:
- Go to the Dedicated Servers/Manage Servers menu
- Choose the server he want to add IPs to
- On the next page, click Add Extra IP(s)
- Fill in the number of IPs you want to add.
