The coordination aspect is in regards to tracing an attack back to the perpetrator. The source prefix-based filtering only disallows an attacker to use bogus source addresses. - paul At 11:10 AM 9/22/96 GMT, Peter Dawe wrote:

ISP implementing filters for packets with false source addresses.

Why does there need to be co-ordination? Surely most ISPs would implement this now they know there is a problem and they can fix it.

We just need to put out a request to ISPs

I would suggest this is done directly rather than through 'bodies' such as IEPG
