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.) - Brian
