A valid netmask is a set of 1s, followed by a set of 0s. The posted netmask (with assumed typo) is: 11111111111000011111111100000000 That does not fit the definition of a netmask and it certainly can't be mapped to a prefix, because the Prefix is calculated by the the number of preceding 1s! -- Sam -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
