While this is not l-k material per se:
Recycling IP addresses quickly is often necessary. Imagine a medium provider
with lets say 240 dialin ports (using up an entire /24) and approx 2-4 calls
going up and down per second on average, more during peak hours.
If you do not recycle IP addresses within a few minutes maximum, you suddenly
need a /23 to double the amount of time before an IP gets recycled,
effectively wasting 256 addresses, just to solve problems which occur when
some fool doesn't close all his TCP/IP connections before logging off.
I agree that the Linux kernel should have some magical way to detect that the
client side IP of an IP connection suddenly belongs to another host, but this
is not as easy as it sounds ;-)
