Host unreachable what's nagios do.

[Giorgio Zarrelli]

 From the manual:

"When hosts change state (i.e. from UP to DOWN), the host reachability  
logic in Nagios kicks in. The reachability logic will initiate  
parallel checks of the parents and children of whatever hosts change  
state. This allows Nagios to quickly determine the current status of  
your network infrastructure when changes occur."

Ciao,

Giorgio
