public abstract class IPAddressSeqRange extends Object implements IPAddressRange
Note that the IPAddress and IPAddressString classes allow you to specify a range of values for each segment.
That allows you to represent single addresses, any address prefix subnet (eg 1.2.0.0/16 or 1:2:3:4::/64) or any subnet that can be represented with segment ranges (1.2.0-255.* or 1:2:3:4:*), see
IPAddressString for details.
IPAddressString and IPAddress cover all potential subnets and addresses that can be represented by a single address string of 4 or less segments for IPv4, and 8 or less segments for IPv6.
This class allows the representation of any sequential address range, including those that cannot be represented by IPAddress.
String representations include the full address for both the lower and upper bounds of the range.

Since a range between two arbitrary addresses cannot always be represented with a single IPAddress instance,
the returned iterator iterates through IPAddressSeqRange instances.
For instance, if iterating from 1.2.3.4 to 1.2.4.5 with prefix 8, the range shares the same prefix 1, but the range cannot be represented by the address 1.2.3-4.4-5 which does not include 1.2.3.255 or 1.2.4.0 both of which are in the original range. Nor can the range be represented by 1.2.3-4.0-255 which includes 1.2.4.6 and 1.2.3.3, both of which were not in the original range. An IPAddressSeqRange is thus required to represent that prefixed range.

If within or above the range, it is the distance to the lower boundary of the sequential range. If below the, returns the number of addresses following the address to the lower range boundary.
The method does not return null if this range does not contain the address. You can call contains(IPAddress) or you can compare with getCount() to check for containment.
An address is in the range if 0 <= enumerate(IPAddress) < getCount().
Returns null when the argument is a multi-valued subnet. The argument must be an individual address.
If the given address does not have the same version or type as the addresses in this range, then null is returned.
