What is the format for specifying multiple IP addresses (is it comma
separated?). It would be good to put that format in this comment. I'd also
mention that these are CIDR ranges and not individual addresses.
```
parser.add_option("--ips-allowed", default="0.0.0.0/0",
help="CIDR IP ranges allowed to access the machine. Multiple ranges
can be separated with commas.")
```
