The exclusive bandwidth means that after the user deploys the server and network equipment to the IDC machine room, it is connected directly with the core device side of the IDC service provider and divides the single subnet to enjoy the bandwidth resources provided by the IDC service provider alone. It is applied to customers with higher requirements for network security, bandwidth quality, and bandwidth scalability. In the server rental or server hosting business provided by IDC service providers, some users have high requirements on bandwidth, and they will buy the corresponding independent bandwidth to make their business develop normally.

　　Exclusive bandwidth refers to enterprises like large and medium -sized enterprises, which have higher requirements for bandwidth. Due to the size and nature of the website, only independent bandwidth resources can meet their quality needs. Bandwidth resources are called exclusive bandwidth.

　　1. View whether the device is connected to the core device of IDC. This model requires users to be familiar with the network architecture of the network service provider, and it also needs to cooperate with the network service provider to achieve cumbersome implementation.

　　2. By allocating to the user's IP address and subnet mask to distinguish. It is generally recommended to operate in this mode. It uses viewing the subnet mask to determine the number of hosts available in the distributed network segment. Generally, the address of the user gets the first place is the network number, the second place is the gateway, the last one, and the last one. The position is the broadcast number, and the other addresses are available addresses. The number of IPs and subnet masks obtained by the user is equal to 256, and the address obtained by the user is exclusive.
