public class MACAddress extends Address implements java.lang.Iterable<MACAddress>
You can construct a MAC address from a byte array, from a long, from a Address.SegmentValueProvider
,
from a NetworkInterface
, from a MACAddressSection
of 6 or 8 segments, or from an array of 6 or 8 MACAddressSegment
objects.
To construct one from a String
use

public MACAddress increment(long increment)
AddressSegmentSeries
If the subnet has multiple values and the increment exceeds the subnet size, then the amount by which is exceeds the size is added to the upper series of the range (the final iterator value) or is subtracted from the lower series of the range (the first iterator value) if negative.
If the subnet is just a single address values, the series is simply incremented by the given value, positive or negative.
If a subnet has multiple values, a positive increment value is equivalent to the same number of values from the iterator. For instance, a increment of 1 is value 1 from the iterator, an increment of 2 is the second value from the iterator, and so on. A negative increment is equivalent to the same number of values preceding the upper bound of the iterator. For instance, an increment of -1 is the last value from the iterator, and increment of -2 is the second last value, and so on.
Therefore, to get the series just above the highest series of the subnet, use an increment of size:count > 1 ? count + 1 : 1
where count is the subnet size.
To get the series just below the lowest series of the subnet, use an increment of size:-(count > 1 ? count + 1 : 1)
where count is the subnet size.

Similar to AddressSegmentSeries.setPrefixLength(int)
except that prefix lengths are never increased.
When this series already has a prefix length that is less than or equal to the requested prefix length, this series is returned.
Otherwise the returned series has the given prefix length.
The bits moved outside the prefix will become zero in the returned series.
