Don't use ip2long/long2ip. It just dosen't work. Do it by yourself with bcmath. Manual page should clearly note the limitation. Changed to doc problem to see if manual is ok. Previous Comments: ------------------------------------------------------------------------ [2001-12-23 06:55:25] [EMAIL PROTECTED] Hi, using ip2long is strange enough itself (would you please do some better description on what I get out after calling this function or at least do some references to documents (RFCs) describing that "IP address in full length notation" format). Anyhow: I'm coding the following <?php $a = base_convert( 0xFFFFFFFF ^ 1, 10 2 ); var_dump( $a ); ?> and get string(2) "10" (under 4.0.6 I got something different: 31 (!!!!) 1's in string without that trailing 0) what about all the other leading bits that should be 1? And in relation with the ip2long-trouble I'm having: <?php $a = base_convert( ip2long( "255.255.0.255" ), 10, 2 ); $b = base_convert( ip2long( "255.255.0.255" ) ^ 0xFFFFFFFF, 10, 2 ); var_dump( $a, $b ); ?> what gives me string(16) "1111111100000001" string(16) "1111111100000000" I beg to get some fast response! This behaviour of ip2long and/or xor-operator is too strange to be easily understood after reading that minimal function reference entry. But I need it a lot for some work that needs to be done urgently!! Thank you very much!
