	Hmm, if the manuals say 4096 then that sounds like a bug.
	A Phase IV DECnet address is 16 bits, 6 bits for the area
	and 10 bits for the node number within the area.  2 to the
	10th power is only 1024 (ie. not 4096).

	VMS's NCP's "copy known nodes" command is VMS specific (ie. its
	not part of the network management architecture for Phase IV).
	The DECnet-ULTRIX equiv. functionality is provided in the
	unsupported update_nodes utility.  If you have V3.0 or later
	then you have to install the unsupported subset first.  update_nodes
	is documented in the release notes with the other unsupported
	utilities.

	Hope that helps.  Merry Xmas and Happy Networking :-)
