Hi Anil,
I'm also new to python and pox field, but will try to help you.
Well, I think it would be better if you look at the packet class code and
check what it does, but it seems that it searches for a 'dns' string inside
the packet received and if find such a string it just "handle" the packet
(you will have to check what 'handle' does). Otherwise it just print "Not a
DNS packet".
Maybe the code "packet.find('dns') is a way to check if it is a DNS
packet or not.
As I told you, I think it would be better if you look at the 'packet'
class.
Hope that was useful.
