Manage DDNS Servers
When end-user devices connect to secure access using the VPNaaS, it is assigned an IP from an IP pool. When the device disconnects and reconnects the VPN, the IP address can change. If the device needs to be reachable using a fully qualified domain name (FQDN), the IP address change can cause the DNS server resource records (RRs) to become stale.
Dynamic DNS (DDNS) provides a mechanism to update DNS RRs whenever the IP address or hostname changes. Add DDNS servers to ensure that changing IP addresses for devices (especially those on dynamic IPs) are automatically updated to provide consistent, reliable access to resources without manual intervention.
When adding these DDNS servers, DDNS Server 1 resolves before DDNS Server 2. Provide DDNS servers that could resolve both IPv4 and IPv6 if applicable. You can also use DDNS for static IP addressing.
