It isn't pure python, but you would be pretty much guaranteed a maintained solution if you use the name server lookup in your OS.  Something like:

	import subprocess
	nsl_reslt = subprocess.Popen(['nslookup', '<insert name nere>' ],stderr = subprocess.PIPE, stdout = subprocess.PIPE).communicate()[0]
