I think he was saying that Delta Telecom don't *own* 62.0.0.0/8 and therefore shouldn't be advertising it. Following that Telia shouldn't be accepting the route and then re-announcing it to peers ...
Of course! ... /8? ... Azerbaijan? ... What was I thinking?...
Still, it would be better to contact the upstream directly and work back through the peering chain because this kind of thing is usually a result of education deficit, not malice.
Probably in theory. In practice, it's not obvious. I *did* get a private response from a Telia person after my posting to Nanog, and this person alerted their routing registry. The 62.0.0.0/8 prefix is now gone - whether as as result of my posting to Nanog or not, I have no means of knowing. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
