ipv4_is_private
Whether an IPv4 address is in a private network: 10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16.
An address with a /mask is cut to its network first. An invalid address gives null.
Syntax
ipv4_is_private(ip)Parameters
Prop
Type
Given a dynamic field
This parameter is string-only. In permissive mode — the default — almost every field arrives as a dynamic, so passing one works because Berserk injects asstring: extract-or-null, the value when it really is a string and null otherwise, so the call yields null (a predicate yields false). A property bag or array is therefore not matched, and tostring() is never applied implicitly — use it explicitly to match a bag's JSON text, keys included. Strict mode rejects the dynamic instead of coercing it. See String coercion and the asXXX family.
Returns: bool

ipv4_is_match
Whether two IPv4 addresses are equal once both are cut to the smallest of their own /masks and the optional prefix (0-32; any other prefix counts as 32).
ipv6_compare
Compare two IPv6 or IPv4 addresses, returning -1, 0 or 1, after cutting both to the smallest of their own /masks and the optional prefix (0-128).
