In staeless, can I use scapy to build dns packet

[xmyy...@gmail.com]

Hi trex,

I have got a question. I want to send dns query packet in stateless mode. I use scapy to build the packet like this,

pkt=Ether()/IP(src=srcip)/UDP()/DNS(aa=1,qd=DNSQR(qname="www.baidu.com"))

But the running result met an error:

pkt=Ether()/IP(src=srcip)/UDP()/DNS(aa=1,qd=DNSQR(qname="www.baidu.com"))
NameError: global name 'DNS' is not defined

Does that mean it not support scapy to build dns packet?
Is there any solution to fix it ?

It works! Thank you!

I have another question.
Can I use " from scapy.all import *" to import scapy all?
I tried，but it dosen't work.
