[44net] Renumbering networks (BGP announced only?)

Hi all. Just got a notice from our network person that he'd received an email from Chris notifying him of a renumbering of our allocated segments. Since I couldn't remember a discussion here (please excuse me if this has been discussed before), I just wanted to raise a few question - out of curiosity. We currently have a few /24 allocations within the 44.141.0.0/16 regional block (Norway). I think two or three of the /24 blocks are published via BGP. In the email, we're requested to renumber, and move the BGP announced segments over to the 44.31.0.0/16 (in the US regional /9 block). I don't think we've heard anything about the other addresses in 44.141.0.0/16 which are not BGP announced? I guess I'm curious about the rationale behind this decision? I think efficiency was stated, but I really can't see any big difference in having a /24 announced either here or there? Since we don't have the same upstream providers as our neighboring nets, there won't be any aggregation benefits (?). Is the plan to also deprecate the national and regional allocations? For our part, quite a few of the devices with 44-addresses are on mountain tops (beacons, remote receivers, sensors, etc.), but we have a 4 month window, starting in a months time, to get up there and do the renumbering. No big deal.. Just curious what the thoughts are.. --Magne / LA1BFA
