Not much details there. I see DNS updates are to be
done by the
coordinators. As they are volunteers, and as they may be very busy, this
may not be compatible with a quick update required by a growing network
But you can be the volunteer yourself!
Our plans were to get a subnet large enough for our
island, and to
manage the "internal" subnetting locally.
You have presented your plans before, and here everyone is wary that a network
on a comparatively small and rural territory like Corsica (330.000 inhabitants)
only used by radio amateurs is not likely to be as large as you picture it.
We all know about the difficulty in getting IPv4 space on internet, but using Net-44
space for a Wireless ISP that just happens to have a couple of radio amateurs in
its admin team is not the way to go.
So you will have to present convincing evidence that this is not what is going on.
I'm wondering about what would be the best
solution :
- Use an independant domain name (ie, "radioamateur.tk")
- Use a subdomain of ampr.org (ie, "corsica.ampr.org"), with a
sub-delegation from the parent "ampr.org" domain
In both solutions, we would have immediate access for local updates, on
our local DNS servers.
Different networks prefer and use different solutions. Some use an independent
domain, some use sub-delegated subdomains, others are directly under ampr.org.
Each of them of course has advantages and disadvantages and each sees it in a
different way.
On the Dutch network we put our addresses directly under .ampr.org and use the main DNS
servers. For updating, I am using a script that automatically sends the updates
to the server based on a local hosts file I update with newly assigned addresses.
Whenever I run the script, which automatically happens once a day, the diff between
the current and previous version is made and all changes are sent to the robot by
mail, and appear in the global DNS some minutes later.
I also download the zone file and keep it locally for use when the internet connection
fails. Systems using our local resolvers (44.137.0.1 and 44.137.0.2)
still have .ampr.org resolution, for those addresses not sub-delegated.
This way I don't have to worry about providing DNS service on internet (which is a
can of worms...) and still everyone has access to our names. Reverse also works,
which is usually a problem on the independent networks.
