Need of 2 $ORIGIN Directives

[Petr Mensik]

A) $ORIGIN changes appended suffix to all hostnames without trailing . for all following records. You can change it more than one time.
Unless I am mistaken, NS records of first section would expand to
. NS local.atlanta.com.
. NS kabulvm8.atlanta.com.

That seems wrong to me.

B) Yes, it is almost equal. NS records are correct this time. I would prefer this variant myself.

However if those zones are output of some tool or script, you should try to support multiple usage of $ORIGIN directive in any tools you use.

Subject: Need of 2 $ORIGIN Directives



Hello, 




We have bind running bind-9.9.4-29.el7.x86_64 




We have a domain file with these configurations and we have to build our A records on top of this 





	
$ORIGIN . 
$TTL 86400 ; 1 day 
atlanta.com IN SOA local.atlanta.com. master.atlanta.com. ( 
2001062522 ; serial 
21600 ; refresh (6 hours) 
3600 ; retry (1 hour) 
604800 ; expire (1 week) 
86400 ; minimum (1 day) 
) 
NS local.atlanta.com. 
NS kabulvm8.atlanta.com. 
$ORIGIN atlanta.com. 
$TTL 300 ; 5 minutes 
local A 127.0.0.1 
kabulvm8 A 10.54.49.43 



So I wanted to understand some things about this Domain 




A. Why are there 2 $ORIGIN directives? 


B. Can the above be replaced as below 





$ORIGIN atlanta.com. 
$TTL 86400 ; 1 day 
@ IN SOA local.atlanta.com. master.atlanta.com. ( 
2001062522 ; serial 
21600 ; refresh (6 hours) 
3600 ; retry (1 hour) 
604800 ; expire (1 week) 
86400 ; minimum (1 day) 
) 
NS local.atlanta.com. 
NS kabulvm8.atlanta.com. 
;A Records 
local A 127.0.0.1 
kabulvm8 A 10.54.49.43 


	





Thanks
