It is a simple program in Python which makes use of the traceroute utility along with the GeoIP database to find out the names of the countries through which a packet is routing.

First of all, download the GeoIP database file from here. Extract the csv file from the zip folder and rename the file as country.csv. Renaming is necessary as the file, in the code below, is referred by this name.

Now make a file traceroute.py(you can give any name to the file, this is just an example) and copy the following code into it.

import socket
import sys
import csv

    def main(dest_name,countries):
        dest_addr = socket.gethostbyname(dest_name)
        port = 33434
        max_hops = 30
        icmp = socket.getprotobyname('icmp')
        udp = socket.getprotobyname('udp')
        ttl = 1
        f=csv.reader(open('country.csv','rU'))
        data = []
        for row in f:
            data.append(row)
        while True:
            recv_socket = socket.socket(socket.AF_INET, socket.SOCK_RAW, icmp)
            send_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, udp)
            send_socket.setsockopt(socket.SOL_IP, socket.IP_TTL, ttl)
            recv_socket.bind(("", port))
            send_socket.sendto("", (dest_name, port))
            curr_addr = None
            curr_name = None
            try:
                _, curr_addr = recv_socket.recvfrom(512)
                curr_addr = curr_addr[0]
                try:
                    curr_name = socket.gethostbyaddr(curr_addr)[0]
                except socket.error:
                    curr_name = curr_addr
            except socket.error:
                pass
            finally:
                send_socket.close()
                recv_socket.close()

            if curr_addr is not None:
                curr_host = "%s (%s)" % (curr_name, curr_addr)
            else:
                curr_host = "*"
            print "%d\t%s" % (ttl, curr_host)
            a=[]
            a=coun(curr_addr,data) ###
            countries.append(a)
            ttl += 1
            if curr_addr == dest_addr or ttl > max_hops:
                break
        return countries

def coun(curr_addr,data):
    countries=[]
    add=curr_addr.split('.')
    #print add
    var=0
    #while data[var] is not None:
    for row in data:
        #print "fdgjdfgdfkg"
        uplimit=row[1]

        lwlimit=row[0]
        uplimit=uplimit.split('.')
        lwlimit=lwlimit.split('.')
        #print uplimit
        #print lwlimit


        if add[0] == uplimit[0]:
            #print "gnvkdfhgkfd"
            if add[1] == lwlimit[1] or add[1] == uplimit[1]:
                if add[2] == uplimit[2] or add[2] == lwlimit[2]:
                    if add[3] == uplimit[3] or add[3] == lwlimit[3]:
                        return row[5]
                elif add[2] < uplimit[2] and add[2] > lwlimit[2]:
                    return row[5]

            elif add[1] < uplimit[1] and add[1] > lwlimit[1]:
                return row[5]
        #else:

    return "country NA"


if __name__ == "__main__":
    countries=[]
    countries = main(sys.argv[1],countries)
    print "The packets are routing through the following countries:"
    for value in countries:
        print value

Now put both the files- traceroute.py and country.csv in the same folder and run the following command in the terminal

sudo python traceroute.py <www.domainname.com>

Provide any domainname without <> and you will see the required output
