Love to be able to have a DO firewall that utilises various selectable blacklists to block those IP's

Add the ability to set the soft and hard limit on some bandwidth usage - to prevent 0.01$ charge for 1GB of exceeding monthly droplet quota

So far, load balancers only get an IPv4 and no IPv6. In practice, this means that load balancers cannot be used if you want to provide IPv6 connectivity. I would love to use this feature, but only if IPv6 was made available.

it'd be tremendously useful to have a comment field for firewall rules in the webui. For example, comment what the hosts/networks are (when the rule was created) or why the rule was added.

Would be very helpful to have a firewall rule that would deny specific IPs. We currently have implement our own blacklist via iptables.

Add ability to change private IP of a droplet in a VPC.

not only droplets but also load balancers should be put behind the firewalls

So it would be great if you can use an API call to your droplet to see how much bandwidth you have left, how much you have used, what your limit is etc.... REST Full API call would be great.

When destroying a droplet there's a 99% chance that you will get your IP back. If someone creates a droplet while destroying/creating a new one and steals your IP, it's a pain, even if the chances are <1%. This 1% is too much for some. An IP is an important number, your server might not be able to send emails if the last IP's user was sending spam through it. Software licenses are also tied to IP sometimes. When I want to rebuild a server (or resize: disk size) I want to make sure that I get my IP back. Please figure out a way so that we don't lose our IP (100% guaranteed) when we destroy/recreate a droplet.
