`public static`	# `ipv4_netmask2cidr( mixed $netmask )`
`public static`	# `ipv6_netmask2cidr( mixed $netmask )`
`public static boolean\|int[]`	# `range2network( integer $start, integer $end )` Parameters `$start` `integer` $start `$end` `integer` $end Returns `boolean\|int[]` FALSE if start/end do not match a network/mask. Otherwise : Array( 'network' => '10.0.0.0', 'mask' => 8, 'string' => '10.0.0.0/8')
`public static boolean`	# `cidr_match( string $ip, string $network, integer $cidr )` Parameters `$ip` `string` $ip `$network` `string` $network `$cidr` `integer` $cidr Returns `boolean`
`public static integer`	# `netMatch( string\|int[] $sub, string\|int[] $ref )` return 0 if not match, 1 if $sub is included in $ref, 2 if $sub is partially matched by $ref. return 0 if not match, 1 if $sub is included in $ref, 2 if $sub is partially matched by $ref. Parameters `$sub` `string\|int[]` $sub ie: 192.168.0.2/24, 192.168.0.2,192.168.0.2-192.168.0.4 `$ref` `string\|int[]` $ref Returns `integer`
`public static &`	# `stringToStartEnd( mixed $value )`
`public static &`	# `IPv6network2StartEnd( mixed $ip )`
`public static string`	# `inet_ptoi( string $ip )` Converts human readable representation to a 128 bit int which can be stored in MySQL using DECIMAL(39,0). Converts human readable representation to a 128 bit int which can be stored in MySQL using DECIMAL(39,0). Requires PHP to be compiled with IPv6 support. This could be made to work without IPv6 support but I don't think there would be much use for it if PHP doesn't support IPv6. Parameters `$ip` `string` $ip IPv4 or IPv6 address to convert Returns `string` 128 bit string that can be used with DECIMNAL(39,0) or false
`public static string`	# `inet_itop( string $decimal )` Converts a 128 bit int to a human readable representation. Converts a 128 bit int to a human readable representation. Requires PHP to be compiled with IPv6 support. This could be made to work without IPv6 support but I don't think there would be much use for it if PHP doesn't support IPv6. Parameters `$decimal` `string` $decimal 128 bit int Returns `string` IPv4 or IPv6 PROBLEM BY USING IT WITH IPV4 0.X.X.X MAYBE AS NETMASK/WILDCARD AS IT RETURN IPV6
