My experience is possibly somewhat limited, I made the statement based on : 1) the default ACLs and route filters for the rather large ISP I used to work for. Unfortunately I don't get a chance to work in the core of that network, so I'm making a judgement on what was supposed to be the practice rather than reality. 2) I logged into router-server.cerf.net, couldn't find any network 10/8 in the bgp and route tables, looked at their incoming BGP route filters, they weren't filtering for it, so their upstream ASs looked to be filtering it. I was mostly wondering if people were over estimating the occurance of RFC1918 route leaks, purely because "they stick out like a saw thumb". With the RFC1918 leaks you see, do they disappear pretty quickly after they appear, indicating somebody took action to stop the leak ? It would also be interesting to see if the origin AS of these RFC1918 leaks is one of the private ones. ps, we can take this off-ML if people don't think it is relevant to IPv6.
