For example, for the IP address 10.17.20.4 and a mask of 255.255.255.0 the subnet is 10.17.20.0 and the host id is 4. The broadcast address within the 10.17.20.0 subnet is when the host id portion of the address is made up of all binary 1s. In this example the host portion is ...
IPv4 had a subnet mask (dotted quad notation) that was later replaced by CIDR masking.IPv6 doesn’t have a subnet mask but instead calls it aPrefix Length, often shortened to “Prefix”. Prefix length and CIDR masking work similarly;The prefix length denotes how many bits of the address d...
Subnet address - the fourth grouping of numbers (the 49th through 64th bits) in the subnet mask Device address - the last four groupings of numbers (the last 64 bits) in the subnet mask For example, in the IPv6 address 2001:db8:abcd:0012:0000:0000:0000:0000, the network address is...
