Check_MK Werk 5945: Hosts can now be configured without IP address

ID: 5945 Title: Hosts can now be configured without IP address Component: Core & setup Level: 1 Class: New feature Version: 1.5.0i4 It is now possible to configure hosts in Check_MK that have no IP address configured. This is useful e.g. in case a host is only monitored using piggyback data from another host. In previous versions of Check_MK a fake IP address had to be configured for each host to prevent warning messages during config generation and during monitoring. To configure a host without IP, simply set the "IP address family" attribute of a host to "No IP". The host check of these hosts will always report "UP" by default. To override this, you can use the rule set "Host check command".
