Re: [44net] DNS Delegation idea / query

Yes of course it is for coordinators - those are the people who are supposed to assign and update the name-address mappings. I think once it was an objective of the portal to enable users to update the entries in their own subnet, but it never materialized. Also I thing a web DNS editor (most of them anyway) is not a useful tool for a coordinator, as they need to have an overview of the entire subnet they manage. When someone asks for an address I have to look what is already there, which subnet is for that area, what ranges are free, and then assign an address or subnet to them as required. That is easy when having the hosts file (which includes comments) in my editor, and much more difficult when I have to browse around in a webtool. DNS delegation fragments the resource. There are several NS records that point to internet addresses, making us dependent on internet for address lookup. This even is the case for ampr.org itself for which only 1 of the 4 servers is on AMPRnet. Also those servers are distributed around the world. This makes ampr.org and 44-reverse lookups quite slow. As we like things to work well, I have an hourly job that checks the DNS serial for the ampr.org zone and when it is newer than our local copy, it retrieves the newest zone files from ftp://gw.ampr.org/pub/ampr.tar.gz and loads them into our own DNS resolver. So anything that is directly in those zonefiles can be looked up quickly on our network, the delegated parts of course remain slow. It would of course be better when we could just IXFR the updates from the master server, but it does not support it. I also tried to do this with some of the delegated servers but most of them refuse transfers. Not very friendly I would say, but likely it is just the default setup for most DNS servers these days. I think they should at least support zone transfer, preferably IXFR, from net-44 addresses.

But last I heard it was available to coordinators only and I've never seen a description of howto use it published at least widely enough that it was seen by the amprnet masses. I can also see security issues with such. I've been asking for DNS zone deligation both forward and reverse for years, and I would fully support such a move. It seems that the case for transfering the entire ampr.org zone is over rated and could still be done by crawling the DNS tree, but why? if you are off line and disconnected you only need DNS for your subnet anyway as you won't be able to reach anything else DNS or not. eric af6ep On 2021-08-14 08:43, Rob PE1CHL via 44Net wrote: This is already there. Some regions and amateurs do run their own DNS. I don't think it is that great, because it makes it impossible to simply transfer the entire DNS zone to a local server and have faster DNS lookups independent of an internet connection. But it works, I guess... IMHO it would be better to offer a DNS update API, where everyone can update their own host records in an easily automated way. It of course exists in the form of the mail robot and also the web DNS editor but apparently some people think it is not good enough. (I use the mail robot myself as part of an automated update) Rob On 8/14/21 5:32 PM, Bill Buhler via 44Net wrote: Just thought of this this morning, and was wondering if we could have a DNS delegation system for hams off of ampr.org or another domain name? Something like: af7sj.ampr.org ns myprimary.dns.server af7sj.ampr.org ns mysecondary.dns.server In my ideal deal world there would be a .radio TLD... or a .44net tld... But would it make sense to offer any ham out there a DNS subdomain based on their call? For those that want to limit access that could also become part of their checks, i.e. does the forward and backward DNS resolve to a subdomain.ampr.org domain? 73 Bill Buhler - AF7SJ _________________________________________ 44Net mailing list 44Net(a)mailman.ampr.org https://mailman.ampr.org/mailman/listinfo/44net _________________________________________ 44Net mailing list 44Net(a)mailman.ampr.org https://mailman.ampr.org/mailman/listinfo/44net
