Atlantic.Net has just joined the 69/8 club of ARIN members with assignments in this IP block that's apparently in numerous outdated bogon filters. As I posted I'd do earlier if given space from this block, I've written some code to check reachability to a large number of remote IPs from 2 source IPs...one in one of our older ARIN blocks, one in the new 69 block.
Welcome. I'm glad to see you on board. Perhaps some of these issues will get resolved for us smaller /18 assignments.
What have others in this situation done?
Are you actually assigning 69/8 IP's to unsuspecting customers and hoping they won't notice parts of the internet ignoring them?
Oh, the customers notice them, and each report is handled as brought to our attention. It's a large net, so we haven't bothered with probing at this junction. I get about 1-3 reports a month from my customers that are due to filters. A few of the lists themselves are out of date, evidenced by networks that were previously working suddenly breaking by applying a new BOGON list. Most cases are smaller networks that are often unaware that they run such filtering. Some don't even know what it is. I didn't have a choice on giving the space to customers. My old IP addresses were being recalled and I get what ARIN gives me. In another month 60%+ of my network will be within the 69/8 and I'll have to request more space which will most likely be from the same block (the last I checked, my /18 could expand to a /17). As far as I'm concerned, the quicker the space is assigned and utilized, the more people we'll have spotting and contacting networks that have bad filters.
I don't know if ARIN has other "less tainted" IP space to give out, but something ought to be said/asked about this at the next meeting. I realize ARIN can't guarantee global routability of IP space, but should they continue to give out IP blocks they absolutely know are not fully routable on the internet today?
In defense of ARIN, the ice on a net block has to be broken at some point. They could wait 3 years and notify every list every hour of every day for those 3 years and there would still be many networks filtering those networks. The only way to catch it is to notice the block and make contact with the network. In many cases, personal contact is necessary as emails are often misunderstood or ignored.
