The name of the PTR record *is* a.b.c.d.in-addr.arpa. You want the 
*value*, which you can get from answer[0].payload.name. e.g.

def printPTR(results):
    answer, auth, additional = results
    if answer:
	print answer[0].payload.name

d = resolver.queryUDP([
	dns.Query('4.3.1.2.in-addr.arpa', dns.PTR)
    ])
d.addCallback(printPTR)

Obviously this code needs more error checking.
