Nice work! I had originally meant to make a patch myself but got
distracted. :)

> Bug description:
> Hi! I was reading the guide on the "Get me a network" bits, and I
> realized that the whole manual is using the wrong address ranges.
>
> RFC5737 defines three ranges for use in documentation:
>
> 3. Documentation Address Blocks
>
> The blocks 192.0.2.0/24 (TEST-NET-1), 198.51.100.0/24 (TEST-NET-2),
> and 203.0.113.0/24 (TEST-NET-3) are provided for use in
> documentation.
>
> These are non-routable addresses, even privately, and the RFC is
> specifically provided to avoid problems like overlap (If everyone uses
> the 10.x ranges because that's what's in the manuals, we end up with
> even more overlap than usual).

> https://tools.ietf.org/rfc/rfc5737.txt
>
> It's worth noting that the manual _is_ compliant with RFC3848, which
> defines the IPv6 documentation range as 2001:db8::/32.
