Re: (MeowChow) Re: Check IP with support for CIDR

Could not get that to work. However, it did make me think and hence this:

return ( (unpack('N',pack('C4',split(/\./,$i))) ^ unpack('N',pack('C4'
+,split(/\./,$1)))) >> (32-$2) ) == 0;

My bad, I forgot to negate the result: `return not unpack ('N', pack ('C4', split /\./, $i) ^ pack ('C4', spli +t /\./, $1)) >> 32 - $2;` [download] MeowChow s aamecha.s a..a\u$&owag.print	[reply] [d/l]
