If an A.P.T. is monitoring the traffic from an IP address, a temporary strategy to confuse the intruders, would be to request local DNS to reassign every IP in the area.
The DOS command file cmd.exd, used to have just such a command.
IPCONFIG /DNSFLUSH used to perform a 15 minute reassignment of IP addresses. Now it clears local browser cache of DNS data.
This is adverse to network security overall.
