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
Take a look at http://www.routes.netaxs.com for the output of an
aggregation suggestor we use. Obviously, there are cases where it's
desired to advertise more specific routes, but we do see many route
advertisements that are probably superfluous.
