DNS query walking

-

does know how dns query tree walking? example, have dns infrastructure this:

123.com

456.123.com

it seems servers or workstations @ 456.123.com , without additional suffix 123.com not find objects @ 123.com. know fix know how dns tree walking. can help?

thank much,

hi ,

in simplification evaluation done right left. dns first search if hosts forward lookup zone of 123.com, if forward lookup zone exist return ip record.

search suffix used client side resolver “suffix” dns query. 
if ping hostname called “servername,” if search suffix has been configured, whether automatically (being joined domain), or manually, “suffix” search suffix query. 

for reference:
