The distance to a Cassandra node as assigned by a com.datastax.driver.core.policies.LoadBalancingPolicy (through its * distance method). The distance assigned to an host influence how many connections the driver maintains towards this host. If for a given host the assigned HostDistance is Local or Remote, some connections will be maintained by the driver to this host. More active connections will be kept to Local host than to a Remote one (and thus well behaving LoadBalancingPolicy should assign a Remote distance only to hosts that are the less often queried).

However, if an host is assigned the distance Ignored, no connection to that host will maintained active. In other words, Ignored should be assigned to hosts that should not be used by this driver (because they are in a remote datacenter for instance).
