I have been told that that is true.  There are more users than they have
IP addresses, that is why they use dynamic IP's, rather than static
IP's.  They scan to see if someone is using the modem, and if they are
not, the IP address is given to someone else.  This allows more people
to use the KS cable with less expense.  This doesn't happen very often
any more since KS cable bought more IP addresses.  This is the story I
was given in my NT and Internet classes @ Butler.  :-}
