	XXXX: EUI64 address
	

• Setup

	Set the DNS Server1(TN)'s address on NUT as above mentioned Network Topology.
	

• Pre-Sequence

	In order to send the query for NS type of example.com to the DNS Server1(TN), 
	NUT is configured.
	

TEST PROCEDURE

	This test sequence is following.

JUDGMENT

        1. Standard query for NS type must be based on above Verification Points.

TERMINATION

        If NUT has cache function, clear the cache.
