This might not be allowed under existing service contracts. Most providers probably have provisions to disconnect for network abuse...but not for cluelessness.
Then we need to re-classify having an open broadcast amplifier as an abuse. If we can get upstreams and backbones to give a formal 30 day notice, then start cutting lines ... OTOH, what about just declaring that X.X.X.{0,255} is off limits regardless of the network size? It would take just 2 access list entries to make those addresses in networks larger than /24 to be mostly useless. There aren't that many LANs out there that would have real non-broadcast use on these addresses, anyway. I block these coming in to my network as destinations, and I'm tempted to block them as sources, as well. Once these addresses are indeed off limits, then the next step is to get backbones to put in the access lists. -- -- *-----------------------------* Phil Howard KA9WGN * -- -- | Inturnet, Inc. | Director of Internet Services | -- -- | Business Internet Solutions | eng at intur.net | -- -- *-----------------------------* philh at intur.net * --
