| j | � d S( sH Initialize an ip4range class. The constructor accepts an unlimited
number of arguments that may either be tuples in the form (start,stop),
integers, longs or strings, where start and stop in a tuple may
also be of the form integer, long or string.
Passing an integer or long means passing an IPv4-address that's already
been converted to integer notation, whereas passing a string specifies
an address where this conversion still has to be done. A string
address may be in the following formats:
- 1.2.3.4 - a plain address, interpreted as a single address
- 1.2.3 - a set of addresses, interpreted as 1.2.3.0-1.2.3.255
- localhost - hostname to look up, interpreted as single address
- 1.2.3<->5 - a set of addresses, interpreted as 1.2.3.0-1.2.5.255
- 1.2.0.0/16 - a set of addresses, interpreted as 1.2.0.0-1.2.255.255
Only the first three notations are valid if you use a string address in
a tuple, whereby notation 2 is interpreted as 1.2.3.0 if specified as
lower bound and 1.2.3.255 if specified as upper bound, not as a range
of addresses.
Specifying a range is done with the <-> operator. This is necessary
because '-' might be present in a hostname. '<->' shouldn't be, ever.
