IP	ip

Converts an IPv4 address from string to an integer. This allows performing mathematical operations with the IP address.

{% capture example %}

var addrA = IP('1.2.3.4')
var addrB = addrA + 1
// addrB = 1.2.3.5

{% endcapture %}

{% include example.html content=example %}

NOTE: IP() does not accept IPv6 addresses (PRs gladly accepted!). IPv6 addresses are simply strings:

{% capture example2 %}

// IPv4 Var
var addrA1 = IP("1.2.3.4");
var addrA2 = "1.2.3.4";

// IPv6 Var
var addrAAAA = "0:0:0:0:0:0:0:0";

{% endcapture %}
