The system has no central server so commands can be launched from any node and they will replicate to all nodes. Juju Juju concentrates on the notion of service, abstracting the notion of machine or server, and defines relations between those services that are automatically updated when two linked services observe a notable modification.
A special case of private link-local addresses is the loopback interface. These addresses are private and link-local by definition since packets never leave the host device. IPv4 reserves the entire class A address block 127.0.0.0 / 8 for use as private loopback addresses. IPv6 reserves the single address ::1.
