[routing-wg]Bogon updates
by Leigh Porter 05 Apr '06

05 Apr '06

Hello folks, Excuse my ignorance in not reading the list before I start posting. We (AS29009) were recently allocated 89.104.32.0/19 by RIPE. This is of course from the 89/8 allocated to RIPE by IANA in June 2005. Unfortunately (well, fortunately as it's a good thing) this /8 was on the Bogons list and it seems that some networks have not updated their Bogon filters causing some parts of the Internet to be unreachable to hosts on our network in this /19. Please could y'all check your Bogon filters an update them! I am finding that on a few networks it is only the odd one or two routers that have old Bogon filters. Thanks all, Leigh Porter UK Broadband
