Availability Ntp Quote by Wendell Odom
““NTP Using a Loopback Interface for Better Availability An NTP server will accept NTP messages arriving to any of its IPv4 addresses by default. However, the clients reference a specific IP address on the NTP server. That creates an availability issue.””
About This Quote
Using a loopback interface lets an NTP server respond to any of its IPs, eliminating client‑side IP binding and improving service continuity.
In simple terms: Loopback solves NTP availability
