IPv6

[common_ground]

Hi does anyone know how to convert an ipv6 address into a long e.g 2001:504:4:: I know you can use ip2long() for an ipv4 address

Thanks for your help.

sorry that should have read
Unfortunately PHP was not built with IPv6 support enabled.

I am reading the ftp.arin.net/pub/stats/arin/ to get the ip addresses for a program I am writing most of them are in a form I can deal with and change to a double value I need for look up purposes. But not the ipv6 values, I was wondering is someone browsing a site is likely to have an ipv6 address and if so will the following return an ipv6 address

    if (getenv("HTTP_CLIENT_IP"))
    {
        $ip = getenv("HTTP_CLIENT_IP");
    }
    elseif (getenv('HTTP_X_FORWARDED_FOR'))
    {

        $ip = getenv("HTTP_X_FORWARDED_FOR");

    }
    elseif(getenv("REMOTE_ADDR"))
    {
        $ip = getenv("REMOTE_ADDR");
    }
    else
    {
        $ip = "";
    }
