- 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.
