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.
Comments and advices from similar situations are welcome.
Both of these approaches have been done by different groups.
Several countries have established national sub-domains,
and had the forward and reverse lookup delegated to their own
DNS servers. I have not heard any complaints about this, so
perhaps it is working for them. Eg,
se.ampr.org and their
140.44.in-addr.arpa domains are handled by them. Note that
the reverse delegation is only done when the block of addresses
are directly routed to the Internet backbone (ie., BGP-advertised).
Likely you would be doing that.
If, however, you chose to remain in the top level of .ampr.org,
as a sub-national coordinator you would likely have access to
the master DNS and could make updates at your convenience.
Updates to the master DNS database are propagated to the
worldwide servers every fifteen minutes, which should be often
enough even for a rapidly growing subnet. The master DNS does
accept complex hostname entries such as
xyz.tk1bi.ampr.org,
or even if
xyz.tk1bi.tk.ampr.org, if for some strange reason
you found the latter preferable. (Remember, callsigns are
worldwide unique, so a national subdomain isn't necessary.)
