Reserved CIDR addresses for the TCP and UDP servers

Last published : Oct 19, 2026

Admins can configure reserved CIDR IP addresses for the TCP/UDP servers. These IP addresses are shared in the DNS response instead of the actual IP address during DNS resolution.

The following are the allowed reserved CIDR IP address ranges:

10.0.0.0/8
172.16.0.0/12
192.168.0.0/16

Note:

Ensure that the reserved IP addresses do not conflict with the following:

IP address configured for TCP/UDP applications at the customer resource location.
Network subnet of the client machines.

Configure reserved CIDR IP addresses

Click Settings, and then click Global Configuration.
In Reserved Network Subnet for Secure Access Agent, click Manage.
In IP CIDR, enter the private IP address range.
Click Save.
