Setup

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

Configure the Server1's (NUT) zone file to response query from TN.

Example of example.com zone file:

$TTL    86400           ; TTL of 1 day
@ IN SOA NS1.example.com. root.example.com. (
	2005081600	; serial
	3600		; refresh every 1 hr
	900		; retry every 15 min
	604800		; expire after a week
	3600		; Minimum TTL of a 1 hr
)
;
	IN	NS	NS1.example.com.
NS1	IN	A	192.168.0.10
;
A	IN	A	192.168.1.10
A	IN	TXT	"DNS TEST"

TEST PROCEDURE

        This test sequence is following.

    DNS Client1 (TN)                       DNS Server1 (NUT)
        |                                      |
        |------------------------------------->|
        |   1. Send standard query             |
        |       QNAME=A.example.com            |
        |       QTYPE=A                        |
        |       QCLASS=*                       |
        |                                      |
        |<-------------------------------------|
        |   2. Standard query response         |
        |       A=192.168.1.10                 |
        |       TXT=DNS TEST                   |
        |                                      |
        v                                      v

        1. TN send standard query QNAME=A.example.com, QTYPE=A, QCLASS=* to NUT.
        2. NUT reply query response w/ A=192.168.1.10 TXT=DNS TEST to TN (Judgment *2)
