There are still a few places in the UI and in some test code that look like
we are splitting on ":" to separate out a host from a port. This is not going
to work on raw IPv6 addresses. I would prefer it if we updated the comment to
say that storm supports IPv6, but there may still be some issues with raw IPv6
Addresses.---
