我有一个CSV文件，其中IP范围与其土地代码一起存储：
"1.0.0.0","1.0.0.255","16777216","16777471","AU","Australia"
"1.0.1.0","1.0.3.255","16777472","16778239","CN","China"
"1.0.4.0","1.0.7.255","16778240","16779263","AU","Australia"
"1.0.8.0","1.0.15.255","16779264","16781311","CN","China"
这可以这样读：
range_start, range_stop, ignored, ignored, country_code, country_name
当用户要求输入特定的IP地址时，我想向他返回与该IP对应的国家代码。例如，1.0.9.10会为中国返回CN，因为它位于1.0.8.0和1.0.15.255.之间
我不知道如何处理。这是我到目前为止所做的，但我怀疑自己是否朝着正确的方向前进：
import csv
with open("GeoIPCountryWhois.csv") as csvfile:
readCSV = csv.reader(csvfile, delimiter = ",")
IP_LOWs = []
IP_HIGHs = []
Land_CODEs = []
Lands = []
for row in readCSV:
IP_LOW = row[0]
IP_HIGH = row[1]
Land_CODE = row[4]
Land = row[5]
IP_LOWs.append(IP_LOW)
IP_HIGHs.append(IP_HIGH)
Land_CODEs.append(Land_CODE)
Lands.append(Land)
whatIP = input("What IP should be looked up? ")
codedex = IP_LOWs.index(whatIP)
landdex = Lands.index(whatIP)
IP_to_Code = Land_CODE[codedex]
IP_to_land = Land[landdex]
print(IP_to_Code)
print(IP_to_land)

使用Convert an IP string to a number and vice versa中的代码，您可以将输入IP转换为数字。然后，您可以将其与开始/结束IP的数字版本进行比较，它们位于CSV的第3列和第4列。
import csv
with open("GeoIPCountryWhois.csv") as csvfile:
readCSV = csv.reader(csvfile, delimiter = ",")
GeoIPs = []
for row in readCSV:
GeoIPs.append({ low: row[2], high: row[3], land_code: row[4], land: row[5] })
whatIP = input("What IP should be looked up? ")
whatIP_long = ip2long(whatIP)
found_range = next((GeoIP for GeoIP in GeoIPs if GeoIP.low <= whatIP_long <= GeoIP.high), None)
if found_range:
IP_to_Code = found_range.land_code
IP_to_land = found_range.land
print(IP_to_Code)
print(IP_to_land)

您可以在处理IP地址时使用库netaddr。
from netaddr import *
IPAddress("1.0.3.255")>IPAddress("1.1.2.1")
#False
然后你可以使用类似的东西：
注意：以下代码未经测试，因为我没有您的数据。您可能必须进行细微更改才能实际运行代码。如果你在运行时遇到任何错误，请在此处发布，我会尽力纠正。
import csv
from netaddr import *
with open("GeoIPCountryWhois.csv") as csvfile:
readCSV = csv.reader(csvfile, delimiter = ",")
whatIP = input("What IP should be looked up? ")
for row in readCSV:
IP_LOW = IPAddress(row[0])
IP_HIGH = IPAddress(row[1])
Land = row[4]
if IPAddress(whatIP)>=IP_LOW and IPAddress(whatIP)<=IP_HIGH:
print Land

与这个问题有点无关，但是重新发明轮子让我失去了两分钱。如果它不是家庭作业或学习项目，您可以使用GeoIP +免费的MaxMind数据库（或付费版本）。代码稳定，经过测试，可以在生产中使用。

假设您只使用IPV4地址，请将点分十进制表示法转换为32位等效表示法。现在，使用第3和第4列中源文件中提供的32位IP地址查找位置。
如果要执行多次查找，要使用的良好数据结构是排序列表。可以使用bisect模块中提供的二分算法执行查找。
请注意，对于未分配的IP地址或私有地址范围内的IP，源数据GeoIPCountryWhois.csv中存在间隙，因此需要进行少量的前期数据按摩。这是一个从文件加载数据的类，填补任何空白，并使用bisect_left()执行查找：
import csv
import socket
import struct
from bisect import bisect_left
def ip2long(ip):
"""
Convert an IP string to long (see http://stackoverflow.com/a/9591005/21945)

packedIP = socket.inet_aton(ip)
return struct.unpack("!L", packedIP)[0]
class GeoIPCountry(object):

self.geoips.append((last_hi+1, ip2long('255.255.255.255'), None, None))
self.keys = [geoip[1] for geoip in self.geoips]
# assert sorted(self.keys) == self.keys

您可以使用IP Find。
import urllib, json
url = 'https://ipfind.co/?auth=ip=' + ip_address;
response = urllib.urlopen(url)
data = json.loads(response.read())
这将返回一个带有ISO国家/地区代码作为属性的JSON对象。
