OK, you have touched on 2 different subjects.
The DNS query is a fallback if you AP doesn't have a stored controller
IP and you don't have layer 2 connectivity between the AP and the
controller or your DHCP option isn't working...
As to the DHCP setup...
It actually depends on what AP your using.
For the old "airespace" AP's, namely the 1010,1020 and 1030 you can
configure it as ascii. If your using AP1200 that is a 1000 series AP.
for the 1130 its "Cisco AP c1130" for the 1242 its "Cisco AP c1240"
If your using 1130's or 1240's you actually have to do option 43 as hex.
I don't use option 60 and it works fine for me in my lab, but I know
some that need it for thier lab to work.
For the 1130's and 1240's your option 43 will look like this.
type=f1
AA=Number of controllers * 4
BB=Hex conversion of first IP
CC=Hex conversion of Second IP
type(AA)(BB)(CC)
if you have 2 controllers.
AA=2*4=08
IP#1=10.126.126.2=0a7e7e02
IP#2=10.127.127.2=0a7f7f02
you would put
option 43 hex f1080a737e020a7f7f02
Ask your cisco SE for the internal Cisco document published on the
wnbu-tme site for configuration guidance if you still have problems.
