Oct 23, 2018 at 12:44 comment added Titus +!! is not required; the OP now accepts arbitrary truthy values.
Oct 22, 2018 at 11:51 comment added Ismael Miguel @nwellnhof After testing, I confirm that that is the case. However, I don't think it is a good idea to use it, since it isn't explicitly documented.

Reduced 1 byte, added more about ip2long
Oct 22, 2018 at 10:46 comment added nwellnhof In newer PHP versions, ip2long doesn't allow incomplete addresses.
Oct 22, 2018 at 10:09 comment added Benoit Esnard Using 5**9 instead of 1<<20 saves one byte here: PHP uses & to test the IPv4 / IPv6 flags, so any number between 1048576 and 2097151 is valid.
