That's really sad. You would think if they aren't going to do any "advanced" filtering, they would at least filter broadcast packets from network ingress. I've even seen ISP's allowing RFC1918 addresses in *sigh*

Similarly at my networks.
Yesterday evening (Jan 29 21:10 GMT+1) a very noticeable stream of such packets started to come into my networks.

All are TCP, from 255.255.255.255(80), destined to various random addresses (even not used) to various port numbers.

This appearance is very noticeable. Before yesterday, single packets from 255.255.255.255 were coming in rate about one for three weeks. Since yesterday there have been about 1680 for 22 hours.
