使用Python脚本抓取aws所有的IP地址

为了满足客户业务需求，需要抓取AWS新加坡所有IP地址来设定路由。AWS官网有专门的链接列出所有IP地址，所以只需要利用脚本筛选出新加坡地址就OK。

所有IP地址链接：https://ip-ranges.amazonaws.com/ip-ranges.json

上述链接中“region”分别代表的意思：区域和可用区 - Amazon Elastic Compute Cloud

aws官网给出的抓取方法：AWS IP 地址范围 - AWS 一般参考

[root@PythonLearn home]# cat get_ips.py 
#!/usr/bin/env python
import requests

ip_ranges = requests.get('https://ip-ranges.amazonaws.com/ip-ranges.json').json()['prefixes']
amazon_ips = [item['ip_prefix'] for item in ip_ranges if item["region"] == "ap-southeast-1"]
ec2_ips = [item['ip_prefix'] for item in ip_ranges if item["service"] == "EC2"]


for ip in amazon_ips: print(str(ip))

区域选择： ap-southeast-1  （新加坡）

类型选择：ip_prefix   （只抓取ipv4）

IP地址会更新，所以脚本可以设置定期运行。
