MNAME :	The <domain-name> of the name server that was the original or primary source of data for this zone.
RNAME :	The <domain-name> which specifies the mailbox of the person responsible for this zone.
SERIAL :	The unsigned 32 bit version number of the original copy of the zone. Zone transfers preserve this value. This value wraps and should be compared using sequence space arithmetic
REFRESH :	A 32 bit time interval before the zone should be refreshed.
RETRY :	A 32 bit time interval that should elapse before a failed refresh should be retried.
EXPIRE :	A 32 bit time value that specifies the upper limit on the time interval that can elapse before the zone is no longer authoritative.
All times are in units of seconds.

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 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 1 hr
)
;
	IN	NS	NS1.example.com.
NS1	IN	A	192.168.0.10
;
	

TEST PROCEDURE

        This test sequence is following.

    DNS Client1 (TN)                       DNS Server1 (NUT)

        |       SOA=NS1.example.com            |
        |                                      |
        v                                      v

        1. TN send standard query QNAME=example.com, QTYPE=SOA to NUT.
        2. NUT reply query response w/ SOA=NS1.example.com to TN (Judgment *2)
