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.

As I think we are done talking about DNS, I have been looking at our routing tables as of late. I am seeing that many providers with blocks of address space do not aggregate the addresses. I think that if this is so, there needs to be something done to fix it.
Once again, we are not even getting a full BGP table and know that if I see problems on a smaller scale, their most be more of these problems out there.
thanks
