Ok, this will probably be as simple as my little training on how to set
up BIND on Windows posted earlier.
I have a zone file named nsQexample.com.zone
Here is the contents...
--BEGIN ZONE FILE-----------
$TTL 900 ; 900 seconds default record (T)ime (T)o (L)ive in
cache
; Question about the NS1 - NS3 record entries below
@ SOA ns1 ( ; ns1.nsQexample.com is the prim srv for nsQexample.com
pmstr ; cntct email for nsQexample.com is
pmstr at nsQexample.com
2005122001 ; Serial ID in reverse date format
21600 ; Refresh interval for slave servers
1800 ; Retry interval for slave servers
604800 ; Expire limit for cached info on slave servers
900 ) ; Minimum Cache TTL in zone records
@ NS ns1 ; ns1.nsQexample.com is a host for nsQexample.com
@ NS ns2 ; ns2.nsQexample.com is a host for nsQexample.com
@ NS ns2 ; ns3.nsQexample.com is a host for nsQexample.com
@ A 10.0.0.2 ; nsQexample.com's IP address is 10.0.0.2
@ MX 10 mail ; Mail for *@nsQexample.com is sent to
mail.nsQexample.com
ns1 A 10.0.0.2 ; ns1.nsQexample.com's IP address is #.#.
#.2
ns2 A 10.0.0.3 ; ns2.nsQexample.com's IP address is #.#.
#.3
ns3 A 10.0.0.4 ; ns2.nsQexample.com's IP address is #.#.
#.4
mail A 10.0.0.2 ; mail.nsQexample.com's IP address is #.#.
#.2
www A 10.0.0.2 ; www.nsQexample.com's IP address is
10.0.0.2
--END ZONE FILE-----------
Now my questions are as follows...
1) Assuming this file is stored on the machine named NS1.NSQEXAMPLE.COM
Would not the entries
@ NS ns2 ...and...
@ NS ns3
...conflict with the @ statement, pointing it to the current server?
2) Equally so, if this file was residing at NS3.NSQEXAMPLE.COM
Shouldn't the initial SOA record entry state ...
@ SOA ns3 ( ; ns3.nsQexample.com is the prim srv for nsQexample.com
...rather than...
@ SOA ns1 ( ; ns1.nsQexample.com is the prim srv for nsQexample.com
