[44net] IRR Entries for BGP Filtering

Hello 44Net friends -- I'm operating a BGP-announced subnet of 44/8 for some paging and SDR experiments, and with some new access to other facilities, I'm looking into adding some geographic redundancy for my network, setting up an ASN, and beginning some public peering. However, what I am coming to discover is that Brian's LOA only gets me so far... :) Many networks in Europe are doing proper per-peer prefix filtering, constructed from IRR data in various registries. I would like to get my 44/8 prefix listed in one of these registries with my ASN listed, so that I can get all this automatic filtering working. Generally, most networks seem to be using the RIR-provided IRR registry for this data, which for us in the US and with AMPR would be ARIN. There are also some commercial IRR databases. https://www.radb.net/ seems to be the most-widely mirrored, but it costs ~$500/year to use. As this is just a hobby project for me, it's difficult to justify the costs of a commercial registry. Might it be possible for AMPRNet users to use ARDC's ARIN accounts to list some "inetnum" IRR data for our prefixes? Depending on the outcome, maybe this would be some useful information to list on the FAQ in the Wiki. Thanks, jof
