Hi, Sean.
] lower bandwidth<---->higher bandwidth
Great ASCII chart. :)
] Of course, there are some exceptions like a customer with an OC192 uplink
] or an ISP running a web hosting center on a ISDN link.
Another bit to consider is address space. Code Red discovered
a lot of folks with very small pipes (circa T1) and very large
netblocks (circa /16). These folks paid a heavy price when
hit with the "scan all IPs in the netblock" worms.
Thanks,
Rob.
