The Internal Private Network (IPN), Cyberport's backbone for Internet access, is a unique IT&T facility unlike standard market broadband products, with 40GB Ethernet uplinks and pay-as-you-go bandwidth to accommodate unanticipated increases in user demand. Tenants receive two IPN ports at 100 Mbps local shared bandwidth free of charge after a one-time installation fee, and can subscribe for GE ports if higher or dedicated international bandwidth is required at a cost of only $1,000/Mbps per month (up to 1Gbps) through the Cyberport Optical Network (CON).
IPN ports can support both IPv4 and IPv6. For IPv6 addresses, a prefix of 48 will be allocated upon request at no additional charge. An 8-IP network (with three usable IP addresses) will be allocated if more fixed IPs per port are required, with an administration fee of HK$120 per month per 8-IP network address. [APNIC regulations restrict us to 16 public IP addresses per tenant; any requests beyond this must be submitted via NOC and HKCMCL to APNIC for prior approval.
