#get_group_instance_ipv4s(instance_id, set = :inside) ⇒ Object

Returns an array containing the ip addresses of all instances in the same security group. set determines which ip addresses are returned. There are 3 possible values :inside is the default value. This returns all inside ip addresses :outside returns all the outside addresses for instances that are natted. :all returns all ip addresses regardless of whether they’re natted or not
