抓取主機的IP(含IPv4和IPv6)

抓取主機的IP(IPv4和IPv6)

Python部份

import socket
addrs = socket.getaddrinfo('www.hinet.net',443)
ipv4_addrs = list(set([addr[4][0] for addr in addrs if addr[0] == socket.AF_INET]))
ipv6_addrs = list(set([addr[4][0] for addr in addrs if addr[0] == socket.AF_INET6]))
print ('first IPv4:', ipv4_addrs[0], ' candidates:', len(ipv4_addrs))
print ('first IPv6:', ipv6_addrs[0], ' candidates:', len(ipv6_addrs))

以上程式碼測試過python 3.5.2和python 2.7.12

輸出為:
first IPv4: 210.61.33.225  candidates: 8
first IPv6: 2001:b000:1e5:1100::8  candidates: 8

BASH部份
