An IPv4/v6 Helper Suite for PHP

dTR-IP

An IPv4/v6 Helper Suite for PHP

Usage:

This class takes both IPv6 (expanded and condensed) and IPv4 addresses into consideration.

You can create the class by passing an IP and CIDR mask one of two ways:

$net = new dTRIP("fe80:dead:15:a:bad:1dea:11:2234/93");
// or
$net = new dTRIP("fe80:dead:15:a:bad:1dea:11:2234", 93);

You can then access different aspects of a network:

$net->getIP(); // returns IP
$net->getCIDR(); // returns CIDR
$net->getNetwork() // return Network ID
$net->getBroadcast() // return Broadcast ID

There is a __toString() method which will return a JSON-encoded string on the class object:

echo new dTRIP("fe80:dead:15:a:bad:1dea::/65");

The above would return:

{
  "ip":"fe80:dead:15:a:bad:1dea::",
  "cidr":"65",
  "netmask":"ffff:ffff:ffff:ffff:8000::",
  "network":"fe80:dead:15:a::",
  "broadcast":"fe80:dead:15:a:7fff:ffff:ffff:ffff"
}

Examples:

Here are some examples:

ipv4

$net = new dTRIP("10.22.99.199", 28);
echo $net->getNetwork(); // 10.22.99.192

ipv6

$net = new dTRIP("fe80:dead:15:a:bad:1dea:11:2234", 93);
$net->getNetwork(); // fe80:dead:15:a:bad:1de8::
$net->getBroadcast(); // fe80:dead:15:a:bad:1def:ffff:ffff

Notes:

Although IPv6 does not use the concept of networks and broadcasts, the ranges are still needed to do inclusive searches. Also, IPv6 has a subnet segment, but can still be supernetted/subnetted, which this takes into consideration.

dtr-ip's Issues

Address in range?

Sorry for the noob question, but how would I use this to check if a given address is in the given range? Would a method inRange() make any sense at all?

ipv4 netmask not working on windows

the bit functions work different in 32 and 64 bit as well as windows, change the function to

function netmask_v4()
{
switch ($this->cidr) {
  case 0:
      $netmask = "0.0.0.0";
      break;
  case 1:
      $netmask = "128.0.0.0";
      break;
  case 2:
      $netmask = "192.0.0.0";
      break;
  case 3:
      $netmask = "224.0.0.0";
      break;
  case 4:
      $netmask = "240.0.0.0";
      break;

      $netmask = "248.0.0.0";
      break;

      break;
  case 22:
      $netmask = "255.255.252.0";
      break;
  case 23:

      break;
  case 29:
      $netmask = "255.255.255.248";
      break;
  case 30:
      $netmask = "255.255.255.252";
      break;
  case 31:
      $netmask = "255.255.255.254";
      break;
  case 32:
      $netmask = "255.255.255.255";
      break;
}

    return dtr_pton($netmask);
}

Add `dtr_mask` function

Create dtr_mask function to convert CIDR to netmask, and viceversa.
