#28754 closed Bug

validate_ipv46_address validator allows IP addresses to begin with a first octet of zero — at Version 1

Description (last modified by frankston)

The regular expression used by the ​validate_ipv46_address validator allows IP addresses to begin with a first octet of zero.

For example the following IPs are incorrectly identified as being valid:
0.1.2.3
0.90.11.2

As a side note the ping command (on Ubuntu at least) sees this as an invalid IP:
~$ ping 0.1.2.3
connect: Invalid argument
