All operators known from C are available, with the following exceptions:
/acts a mask operator (see below) when the left operand is an IPv4 or IPv6 address, e.g.
220.127.116.11are all equivalent.
The following new operators have been added:
Note that there is a syntactical ambiguity between the zero IPv6
::) and this form of the mask operator. It is
therefore recommended to always put a space between the two colons
if using the mask operator.
Operator precedence is exactly as in C. In order to leave the precedence of C operators undisturbed, the mask operator and unit qualifiers have been given the highest precedence, while host, host4, host6, and precond can be used like functions.
