I'm glad it worked out for you and that some hams are able to use the process. I might have just been unlucky. I believe Chris is the person who handled my request, since it was for a block to announce, but I can't remember for sure and I've deleted the emails long ago. I worked out another way to accomplish what I want to do, so I'll leave a /24 for someone else to potentially have.

The AMPRnet system is not really, or at least doesn't seem very, approachable for a bunch of reasons, so it doesn't surprise me that hams might not be fully taking advantage. And even once you get a block, using it on the Internet is more difficult than it needs to be. ARDC went to the trouble of having the parent net moved under ARIN's management (changing it away from Legacy status, another self-own), yet ARDC still won't use delegations or IRR/ROA for whatever reason. It all just seems backwards.

I'm licensed and finally have an awesome internet connection. I'd be interested to try this out and see how it goes.
