Ifconfig bad usage in ispcp-net-interfaces-mngr causes networking problems

[aseques]

ispcp-net-interfaces-mngr is using CMD_IFCONFIG as the method to add and remove ip address from the interface.
The problem with ifconfig is that it uses classes by default, so when you add the ip 50.123.123.123, in reality it adds 50.123.123.123/8, so you just lost your connection to 16777214 hosts.
There are two different approaches to this, you can change it from:

$rs = sys_command("$main::cfg{'CMD_IFCONFIG'} ${ip_card}:${ip_id} ${ip_number} up");

To:

$rs = sys_command("$main::cfg{'CMD_IFCONFIG'} ${ip_card}:${ip_id} ${ip_number} netmask 255.255.255.255 up");

Or use the non-obsolete command iproute:

ip add ad ${ip_number}/32 dev ${ip_card}:${ip_id}

ifconfig eth0 50.123.123.123

ifconfig will be replaced by ip

some typos in the version above, it should be

line 88f:

push_el(\@main::el, 'virtual_netcard_add()', "ip addr add ${ip_number}/32 dev ${ip_card}");
$rs = sys_command("ip addr add ${ip_number}/32 dev ${ip_card}");

line 119f

push_el(\@main::el, 'virtual_netcard_remove()', "ip addr del ${ip_number}/32 dev ${ip_card}");
$rs = sys_command("ip addr del ${ip_number}/32 dev ${ip_card}");

Note: Netmask issue should be review. 32 is bad.
