What is an address space?
An address space specifies a range of IPv4 and IPv6 subnets and DNS names grouped as a single object. You can create dynamic address space for Zoom and Office 365 applications using their auto-discovery URL and configure the frequency to perform the discovery run. You can also create custom address space objects by manually adding a static list of addresses for SaaS applications such as WebEx. You can associate the address space to the network access resource to include or exclude application traffic from VPN using split tunneling. The traffic will then pass directly to the public internet instead of being routed over the tunnel.
The system provides a pre-configured default-all address space that contains all the IPv4 and IPv6 addresses and DNS names grouped together. You cannot delete the default-all profile.
You can create the following types of address spaces:
- Custom: Select Custom to manually add a static list of addresses to the address space. To configure WebEx address space, use this option. These addresses are not updated periodically.
- Zoom: Select Zoom to use Zoom’s auto-discovery URL for selecting IP addresses and DNS names. These addresses are updated dynamically.
- Office 365: Select Office 365 to use Microsoft Office 365’s auto-discovery URL for selecting IP addresses and DNS names. These addresses are updated dynamically.
