这是我的第一个python脚本（一般为脚本和编程）。我有一个IP列表，我想对每个IP进行反向挖掘。我发现最简单的方法是编写python脚本来做到这一点。输出看起来没有希望。有人可以指出我在做什么错。 TIA
from subprocess import call
f_file = open("NET-DNS.txt", "r")
for IP in f_file.readlines():
call("dig @4.2.2.2 ANY -x " + IP + "+short")
f_file.close()
输出：
; <<>> DiG 9.12.3 <<>> @4.2.2.2 ANY -x 98.138.219.231
+short
; (1 server found)
