Global name 'IP' is not defined

[Drqonic]

I execute the script on my localhost but it just says this

Sending...
Exception in thread Thread-5:
Traceback (most recent call last):
File "/usr/local/lib/python2.7/threading.py", line 801, in __bootstrap_inner

packet = IP(dst=ntpserver,src=target)/UDP(sport=random.randint(2000,65535),dport=123)/Raw(load=data) #BUILD IT
NameError: global name 'IP' is not defined

is there a fix to it?
