---------------------------------------
Summary: InetAddressValidator IPV4 rejects IPs with leading 0's in
octets
Key: VALIDATOR-421
URL: https://issues.apache.org/jira/browse/VALIDATOR-421
Project: Commons Validator
Issue Type: Bug
Components: Routines
Affects Versions: 1.6
Reporter: Matt Kusnierz
According to Wikipedia "It [IPv4] also allowed the numbers to be written in
hexadecimal and octal, by prefixing them with 0x and 0, respectively", but
org.apache.commons.validator.routines.InetAddressValidator.isValidInet4Address(String)
rejects IPs if an ipSegment starts with a leading 0.
So leading 0's should be detected first, and then used to try and partInt using
the octal radix.
The ipv4 regex also doesn't support hex notation.
