Exclude range of IP addresses from datatable

I am displaying data in a grid that contains a coulmn to display IP addresses. I use a data table to bind the grid. User can select to exclude a facility and the facility is identified by a range of IP addresses.
I need to be able to filter data table rows and remove all rows where IP address is in the range of, say, from 10.20.1.xxx to 10.20.15.xxx as well as 10.20.61.xxx. (i.e. exclude 10.20.1.xxx, 10.20.2.xxx, 10.20.3.xxx, ..., 10.20.14.xxx, 10.20.15.xxx and 10.20.61.xxx).
