Archive Have a look in the archives for the new version 0.41, with the capability to deaggregate network ranges In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 - 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4.
