备忘录：域名扫描以及字典生成

之前无聊扫了点三字符的.de域名，于是写了这个域名扫描的流程做个备忘录

域名扫描程序

1.uselibrary/DomainCheck: Check the available domain of a TLD with dict, based on Python.

2.dynos01/DomainScanningTool: A bulk domain scanning tool

都是基于python

字典生成

1.全球Whois查询 - 天天hu，天天新米 (tian.hu)

2.写了个python脚本来生成aabb/abab类域名，可自行修改调整

import string
import itertools

letters = list(string.ascii_lowercase)
def generate_aabb():
  results = []
  for a in letters:
    for b in letters:
      if a != b:
        results.append(a + a + b + b)
  return results

aabbs = generate_aabb()

with open('aabbs.txt', 'w') as f:
  for aabb in aabbs:
    f.write(aabb + '\n')

print('结果已保存到aabbs.txt')

修改append就可以换生成的类型了，其他变量自行修改即可
