Function
cidr_match — test if IP is in a network
Synopsis
cidr_match(network: net, val: any) -> bool
Description
The cidr_match function returns true if val contains an IP address that
falls within the network given by network. When val is a complex type, the
function traverses its nested structure to find any ip values.
If network is not type net, then an error is returned.
Examples
Test whether values are IP addresses in a network
# spq
values cidr_match(10.0.0.0/8, this)
# input
10.1.2.129
11.1.2.129
10
"foo"
# expected output
true
false
false
false
It also works for IPs in complex values
# spq
values cidr_match(10.0.0.0/8, this)
# input
[10.1.2.129,11.1.2.129]
{a:10.0.0.1}
{a:11.0.0.1}
# expected output
true
true
false
The first argument must be a network
# spq
values cidr_match([1,2,3], this)
# input
10.0.0.1
# expected output
error({message:"cidr_match: not a net",on:[1,2,3]})
