Greetings NANOGers, Yes, I know it has been many years since I have been more than a lurker here on the NANOG list. It is gratifying to see the group continue to facilitate discussions among those that "get it done" in keeping the Internet up and running. Recently, I have moved back into a more operational role and I hope to renew my involvement here as I settle back in. So, to the point of my note: Bogon filter updates! I want to tell you that I am very appreciative of those operators out there that follow the changes in status of IP space and keep there BOGON filters updated. Unfortunately, it appears that there are many that are not doing this regularly. I have been working on getting BOGON filter updates for the 174/8 space (IANA allocated this to ARIN back in February) with upwards of 35 providers (some of the Tier 1 providers are among these) over the last several weeks. Please help me (and others who are getting allocations) by reviewing your BOGON filters and insure you are really filtering out BOGONs and not space that is allocated. If you need a pointer, the authorataive list is maintained at http://www.iana.org/assignments/ipv4-address-space. Thanks for your attention and I hope to see some of you at an upcoming NANOG meeting.
