Thanks for all of the suggestions we have received. If I had only known that talking about ARIN on NANOG was the hot button, I would have pressed it a long time ago :-) I do have some operational factoids to add - my prior post was incomplete. We are multi-homed in a carrier neutral data center. It is imperative that we have our own IP. I do have some small bits of CIDR from other ISPs and have already migrated some of the problem customers to other blocks, but I am not meeting my SLAs with those customers, because we guarantee multiple paths. On IP that belongs to an upstream of ours, traffic only comes inbound through that upstream. That is a problem. Sorry if talking about ARIN is off the topic of this list, but the 69/8 CIDR is "broken" (in customer terms) in lots of places on the internet. ARIN is the one assigning it. If they keep assigning it before everyone's access policies recognize it as valid, this "non-operational" issue is going to cost a lot of people a lot of money in wasted time, effort and resources. I know it has been very painful for us. -----Original Message----- From: Todd A. Blank Sent: Friday, December 06, 2002 10:23 AM To: nanog@merit.edu Subject: Re: Operational Issues with 69.0.0.0/8... The list of inaccessible sites continues to grow: Add to the list www.oandp.com - that looks like someone's firewall filtering in front of their DNS server, because we can't even resolve the DNS. We still can't get to www.ocas.com, www.lavalife.com, and www.indofilms.com even after calling and posting repeatedly. There are undoubtedly others out there. Repeated problems posted by myself and others show the extent of the problem with the 69.0.0.0/8 CIDR, and its lack of dependability - it's a human thing. It used to be restricted, so there are a lot of access lists out there - with all the stuff going on in the last year or so, half the people blocking it probably don't even know how to unblock it - i.e. that person no longer works here... If you look at the address space on IANA, http://www.iana.org/assignments/ipv4-address-space you will see that the last CIDR ARIN took before 69/8 was over a year prior to the 69/8 assignment. A lot happened in our industry in that year. Somewhere, this process is broken since the last CIDR was assigned to ARIN. My question is as follows - We are losing customers because of this problem. It is costing us reputation and money. It is out of our control. If you were us, what would you do? We have already asked ARIN to reassign us to a "friendlier" CIDR, and they refuse. Suggestions are welcome. Sincerely, Todd A. Blank CTO IPOutlet LLC 614.207.5853
