Manage DNS and DDNS Servers

DNS (Domain Name System) is a protocol that translates (resolves) a user-friendly domain name, such as www.cisco.com, to an IP address so that users can access computers, websites, services, or other resources on the internet or private networks.

DDNS (Dynamic DNS) service updates the mappings of domain names to IP addresses to provide accurate IP addresses to DNS clients. When a remote user's network IP address changes, Secure Access can use DDNS to update its system with the new IP address, maintaining seamless connectivity.
