getNetworkBitCount

public int getNetworkBitCount()

Description copied from interface: IPSubnet

Returns the number of bits used for the network address. This number is equal to the number of bits in the address (32 or 128) minus the number of bits used for the host. This is the same as the number that comes after the "/" in CIDR notation

Specified by:

getNetworkBitCount in interface IPSubnet<IPv4Address>

Returns:

number of bits in network

getNetworkMask

public IPv4Address getNetworkMask()

Description copied from interface: IPSubnet

Returns the network mask in address form

Specified by:

getNetworkMask in interface IPSubnet<IPv4Address>

Returns:

network mask of this subnet

getHostBitCount

public int getHostBitCount()

Description copied from interface: IPSubnet

Returns the number of bits used for the host part of the address. This number is equal to the number of bits in the address (32 or 128) minus the number of bits used for the network

Specified by:

getHostBitCount in interface IPSubnet<IPv4Address>

Returns:

number of bits in the host part of the subnet

getNetworkAddress

public IPv4Address getNetworkAddress()

Description copied from interface: IPSubnet

Returns the address of the network (with all host bits set to zero) same as IPSubnet.getFirst()

Specified by:

getNetworkAddress in interface IPSubnet<IPv4Address>

Returns:
