public class IPAddressDivisionGrouping extends AddressDivisionGrouping implements IPAddressStringDivisionSeries
With the IPAddressSection subclass, each division is one segment (eg either groupings of 4 like 1.2.3.4 or groupings of 8 like 1:2:3:4:5:6:7:8).
For IPv6, a compressed segment still counts as one of the groupings, it is simply not printed as part of the text representation.
Alternative groupings include ipv4 groupings define by inet_aton (eg groupings of 1, 2, or 3 divisions like 1, 1.2, and 1.2.3) and the mixed ipv6/ipv4 representation of ipv6 addresses (eg a grouping of 10 divisions like a:b:c:d:e:f:1.2.3.4)
IPAddressDivisionGrouping objects are immutable. Some of the derived state is created upon demand and cached. This also makes them thread-safe.
IPAddressDivisionGrouping objects may be associated with a prefix length, in which case that number of bits in the upper-most portion of the object represent a prefix, while the remaining bits assume all possible values.

IPAddressDivisionGrouping(IPAddressDivision[] divisions,

If the grouping is prefixed, then note that we allow both null:null:x:0:0 where is x is the division bit count and null:null:0:0:0 which essentially have the same overall prefix grouping prefix.

AddressDivisionSeriesTypically this is the largest number of bits in the upper-most portion of the section for which the remaining bits assume all possible values.
For IP addresses, this must be explicitly defined when the address is created. For example, 1.2.0.0/16 has a prefix length of 16, while 1.2.*.* has no prefix length, even though they both represent the same set of addresses and are considered equal. Prefixes can be considered variable for any given IP addresses and can depend on the routing table.
The methods AddressDivisionSeries.getMinPrefixLengthForBlock() and AddressDivisionSeries.getPrefixLengthForSingleBlock() can help you to obtain or define a prefix length if one does not exist already.
1.2.0.0/16 and 1.2.*.* both the same equivalent and minimum prefix length of 16.
For MAC addresses, the prefix is initially defined by the range, so 1:2:3:*:*:* has a prefix length of 24 by definition. Addresses derived from the original may retain the original prefix length regardless of their range.
