Subject: Re: BCP38 is hard, was TWC (AS11351) blocking all NTP?Why does it have to be hard? Restricting the filter to addresses which (A) the customer asserts are theirsHow does the customer do that in a way that scales? I don't think any of this is rocket science, but it apparently is a real block to BCP38/84 implementatin.
Well, there are two issues: how many exceptions at the transit layer will actually be needed, in practice... and how much trouble will there still be there if we can get appreciable uptake at the edge?
