How to tell IP address of remote machine?

[Timothy Murphy]

I had a little program which I ran each day
as a cron job to mail me the IP address of a machine
in a different country.
I give the program sm.py below;
I can't remember where I found it.

In any case, the program has ceased to work
because the site heliohost seems to have gone off-line.

I wonder if anyone knows of an alternative site
which I could substitute?
Or an alternative program?

-------------------------------------
SENDMAIL = "/usr/sbin/sendmail"
import os
import socket
import urllib2
import sys
import time
tt = time.ctime()
response = urllib2.urlopen("http://darkstar.heliohost.org/ip.php")
ipaddr = response.readline().split('<')[0]
f = open("mylog.txt", "w")
f.write(ipaddr + " " + "on" + " " + tt + "\n" )
f.close()
p = os.popen("%s -t -fgayleard at alice.it" % SENDMAIL, "w")
p.write("To: gayleard at eircom.net\r\n")
p.write("From: Timothy Murphy <gayleard at eircom.net>\r\n")
p.write("Subject: Anghiari IP address\r\n")
p.write("\r\n")
p.write(ipaddr + "\r\n")
p.close()
sys.exit()
-------------------------------------
[tim at althea ~]$ sudo cat /etc/cron.daily/ip-address
#!/bin/sh

/usr/bin/python /home/tim/sm.py
