There is a HUGE problem with regards to this. When I look at "certain"
providers and the way they are advertising, this is very common:
206.79.0.0/16
206.79.108.0/24
206.79.224.0/22
etc etc.
They are advertising their 16 right, and then are putting more specific
routes in afterwards. Doesn't make much sense, however I can see certain
situations why it is happening..
In certain circumstances, the people will advertise every class C in a /16 as
well as advertising the /16. It's turned into something worse than pre-CIDR.
The above addresses are Exodus Communications. I don't want to turn this
into a pointing of fingers thread.
