Chris, I am replying to the group although my question will not be of interest to many others, apologies to most of you!
I have been silently following the discussions but too shy to ask, until now, what is happening in the UK? I have been out of the hobby for some years but may get back in (retirement pending) ... we had a few active stations in the Cambridgeshire area but when interest dropped the regional rep closed his gateway down of course. I would assume that management of the DNS for our entries would have delegated back upwards but I am not sure who to. I think the addresses we used were in the 44.131.29.0/24 range, from memory. It would be nice to think that we could just switch on again one day and carry on using those addresses but if there's a shortage of addresses in that range then I suppose that we should release them; however I suspect that isn't the case locally!
Do you know what the delegation chain (if I can call it that) is, down to our range/subnet?
As an observation, the allocation system we had seemed to be a little like a manual, heirarchical version of DHCP, with addresses allocated as needed by local agents who updated the DNS for you and in turn made requests for required subnet address ranges to agents higher up the chain. This thought makes me wonder if something like DHCP/DDNS might have a role in managing DNS in Amprnet?
Sorry to clutter the list, 73
