I wasted an hour trying to figure out how I converted `index.md` to
`index.html` (`pandoc`? `hugo`?), only to discover that it was never the
true source, I had merely converted then cut-and-pasted to the
hand-curated `index.html`.
Also modified simple so that _unit_ would pass and _integration_ would
fail. If swapped, then _unit_ would fail and _integration_ would never
run.

When queried with a mixed-case domain, e.g. "SsLiP.Io", the A and AAAA
records are properly returned. Previously they weren't. This is a
problem when Let's Encrypt queries with a mixed-case domain, which it
does for reasons which are not clear:
<https://github.com/letsencrypt/boulder/issues/1243>
fixes:
```
Failed authorization procedure. sslip.io (http-01): urn:acme:error:unknownHost :: The server could not resolve a domain name :: No valid IP addresses found for sslip.io
```
- cert is from LetsEncrypt
- Hetzner already "owns" the IPv6 version
- For simplicity, it should also own IPv4
This marks a milestone in the sslip.io; its original purpose was to use
a wildcard certificate, and now we're hosting the domain using a
LetsEncrypt certificate. My, how the world has changed.
- Like xip.io, except
- allow dashes as well as dots
- allow IPv6
- allow branding
- allow wildcard TLS
We deprecate the old message, which was about using SSL.
Instead, we use a filler "x{0}", i.e. "'x' appearing exactly
zero times" to separate the parentheses.

- `dashed` domains only (e.g. only "fe80-2a01-4f8-c17--de0e" not
"fe80.2a01.4f8.c17..de0e"; DNS doesn't allow two dots next to each
other.

Admittedly it's overkill to use RSpec to run a set of assertions against
a DNS server -- a simple shell script would have been shorter and more
understandable. We are using RSpec merely to practice using RSpec.
Also, RSpec is not quite appropriate because we're not testing a Ruby
class. In fact, we're not test Ruby code at all. So we should not be
using RSpec. Just sayin'.
