	Firstly what does this have to do with comp.protocols.dns.bind?

	Secondly this is part and parcel of being on the Internet.
	Changing IP will not prevent you being scanned.

	It a big bad world out there where everyone with a computer
	is your neigbour and they can all rattle the door knob.  Make
	sure all the doors are locked that should be locked and move

	In otherwords make sure your system is secured.  Don't run
	applications you don't need.  Use firewall(s) (always on
	the machine and additionally a standalone box) to block
	unauthorised access.  There are many ways for a machine
	behind a standalone firewall to get compromised.  You need
	to protect yourself from unathorised access from other
	machines behind the standalone firewall (there are some
	network programs that only need to be reached from the
	machine itself).

	Keep the applications and OS you do use up to date.  Get
	on the announcement lists for the applications you do use
	so you are informed when there is a problem.

	Get on the local CERT's announcement list.
