Review Comment:
@DaanHoogland
I added a test below
```
System.out.println(NetUtils.isValidIp4Cidr("0.0.0.0/32"));
System.out.println(NetUtils.isValidIp4Cidr("0.0.0.0/0"));
System.out.println(NetUtils.isValidIp4Cidr("0.0.0.0"));
System.out.println(NetUtils.isValidIp4("0.0.0.0"));
```
and got the result
```
true
true
false
true
```
the global setting descriptions says 0.0.0.0 is not valid. it looks like we
need to exclude 0.0.0.0 in line 410, agree ?
Question, is `0.0.0.0/0` or `0.0.0.0/32` valid ?
