What is a benefit of using DDNS?

  • DDNS has a service called ICANN Lookup used to obtain the registration record of a URL.
  • DDNS is a more secure version of DNS and has a robust security profile.
  • DDNS is a starting point for identifying potentially dangerous internet locations that may have been reached through the network.
  • The DDNS provider detects a change to the client IP address and immediately updates the mapping change.

Explanation: Dynamic DNS (DDNS) allows a user or organization to register an IP address with a domain name as in DNS. However, when the IP address of the mapping changes, the new mapping can be propagated through the DNS almost instantaneously.
