----- Text sent by Erik-Jan Bos follows ------- This message is to inform you that SURFnet will stop announcing 192.87.108.0/22 somewhere this week. Instead we will be announcing the following four CIDR blocks: - 192.87.0.0/16 (256 Cs, of which 192.87.108/22 is part) - 145.0.0.0/9 (128 Bs) - 145.128.0.0/10 (64 Bs) - 145.192.0.0/11 (32 Bs)

Soon we will stop announcing some (and later on: all) of the explicit routes inside the four mentioned CIDR blocks. It depends on several external factors who quick we will proceed. But the fact that SWITCH will talk BGP4 real soon now, is very important for this!

Erik-Jan, Thanks to SURFnet for this good news. I know from Thomas that SWITCH has similar plans. Would it be possible to know what are the plans of DFN, JANET, RENATER, GARR and other major service providers ? Any date ? Hope to ear from them very soon. We are close to 20,000 routes in Europe now :-) Time is now to use CIDR in production! -- Jean-Michel
