Is wildcard_dec in processWithSlash function wrong when IP is valid IPv6?

[Wjj954628981]

$wildcard_dec = pow(2, (32 - $netmask)) - 1;
Is 32 should be 128?
And how large number calculate with '&' ?
Thank you.

There is problem with hexadecimal numbers in v6 ips. See

php-ip-tools/src/Ip.php

Line 199 in 6c050df

$range = sprintf(

"%u" will produce decimal number and change your ip.
