Using IPv6 instead of IPv4

[blackVanilla]

Hi,
first - thx you for that script - it's very simple!
And a problem - script uses IPv6 address instead of IPv4 and it's not asking which ip to use.
That issue is on OVP host with venet0 and venet0:0 interfaces (i've tried to change rules in .sh and change address in client config, it's connecting but network isn't avialable)
