多租户 iPSK 子网与 DHCP 作用域设计器

使用 Identity Pre-Shared Keys 为公寓和学生住宅网络规划 IP 分配和 DHCP 参数。

规划您的子网分配

1. Base IP address range

Enter the starting private IP address block for the property.

2. Number of units

Total isolated resident apartments or student flats in the building.

3. Devices per unit

10 Devices
Expected limit of smart home, gaming console, and mobile devices per apartment.
Calculated parent network block
10.0.0.0/21

To support 100 units with up to 10 devices each, you need 16 IP addresses per unit. This requires allocating a parent network of 2,048 total IPs.

Subnet Mask per Unit255.255.255.240 (/28)
Usable IPs per Unit14 usable
Allocated IPs Total1,600 / 2,048
DHCP Lease Time24 Hours

适用于物业运营商的技术网络设计

Identity Pre-Shared Keys 允许多租户物业托管单个 SSID，同时将每个公寓的设备隔离到其专属的私有 VLAN 中。该设计器可帮助工程师规划父 IP 空间大小、定义 DHCP 作用域并分配干净的子网。

网络设计变量

  • 针对智能家居和游戏设备，为每个公寓单元提供 VLAN 隔离。
  • 合理规划 DHCP 作用域租期，防止地址耗尽。
  • 为主流企业级无线控制器直接生成配置模板。

Planning multi-tenant WiFi?

Deploying isolated subnets using iPSK or PPSK secures tenant devices under a unified SSID. Purple simplifies property onboarding, billing, and resident portals.
