func IsAnySourceCIDR ¶
IsAnySourceCIDR reports whether cidr parses to a /0 prefix (covers every address), e.g. 0.0.0.0/0 or ::/0, which leaves a LoadBalancer open to the entire internet despite a non-empty source-range list. Unparseable entries return false: an invalid CIDR cannot widen exposure because the cloud LB would reject it before the source-range list takes effect.
Limitation: this matches only a literal /0 prefix. It does not detect a union of narrower subnets that together cover the whole address space (e.g. 0.0.0.0/1 + 128.0.0.0/1) — a deliberate-evasion case nobody hits by accident, left as a documented limitation rather than expanded into range-union math.
