I'm trying to find all causes of multiple origin AS problem(MOAS) as
follows, but not sure if it's complete. Also please let me know how popular
each item is, especially item 3 and 4 that I'm very curious about.
1. Internet Exchange Points, we have observed a list of this prefixes,
although they generally are not announced to the DFZ.
2. Anycast, rare, but occurs sometimes, for example, 220.127.116.11/24,
2002::/16, and 2001::/32
3. Multi-homing with Private AS number
4. Multi-homing using static route (customer doesn't have AS number)
7. What else?
