This regular expression is validated for both ipv4 and ipv6.
Here is an example of the data that this regular expression passes through.
2001:db8:abcd:0012:0000:0000:0000:0000
0000:0000:2001:DB8:ABCD:12::
255.255.255.0
But this regular expression does not pass validation for such addresses where the prefix is ​​used.
For example, like here
2001:db8:abcd:0012::0/112
How can I add the ability to enter a prefix?
