Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1298299
Description of problem:
Occasionally a customer may want to deploy hosts to a fragmented subnet where several free "holes" exist. In a subnet definition, as it looks today, it is only possible to define a single range in a subnet in which the satellite can create hosts. The ability to specify multiple ranges would be useful

Version-Release number of selected component (if applicable):
Satellite 6.1.5

Additional info:
The issue can currently be worked around by manually reserving the used IP:s in the DHCP configuration. Nevertheless, the ability to do this using the web UI would be nice.
