多租戶 iPSK 子網路與 DHCP 範圍設計工具

使用 Identity Pre-Shared Keys 為公寓和學生宿舍網路規劃 IP 分配與 DHCP 參數。

規劃您的子網路分配

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

專為物業營運商提供的技術網路設計

Identity Pre-Shared Keys 允許多租戶物業託管單一 SSID，同時將每個公寓的裝置隔離到各自的私有 VLAN 中。此設計工具可協助工程師規劃母 IP 空間大小、定義 DHCP 範圍並分配乾淨的子網路。

網路設計變數

  • 針對智慧家居與遊戲裝置，提供每個公寓單位的 VLAN 隔離。
  • 規劃 DHCP 範圍租約大小，以防止位址耗盡。
  • 為主流企業級無線控制器直接生成設定範本。

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.
