Geoff, Thanks for your concern. We are well aware of the problem and expect to make changes in the coming months. Feel free to contact me off-list if you would like to discuss this further.

Perhaps use of NO EXPORT when announcing the more specifics to your upstream transit providers would be a globally helpful action to consider. regards, Geoff Huston At 02:09 PM 2/25/2003 -0800, Hsu, Vicky wrote: -----Original Message----- From: Chan, KaLun Sent: Thursday, February 20, 2003 4:18 PM To: Chan, KaLun; DL NOC Managers; DL NOC-IP Services Cc: Eisenhart, William; Minter, Daniel; DL Neteng-core-ip Subject: RE: [ARIN-20030123.943] 69.3.0.0/Covad - who had this block before? All, It has recently come to our attention that many Internet routers are still filtering out IP addresses in the 69.0.0.0/8 range. If YOU are still filtering this block in your router, please modify your filters accordingly.
