I’m looking for the equivalent of <?php $_SERVER['REMOTE_ADDR'] ?> in Google App Engine and Python.


I slapped a quick and dirty example together based on the tutorial. It’s been tested on my local appengine sdk. You should be able to adapt it to your needs:

from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from google.appengine.ext import db

class Log(db.Model):
    access_time = db.DateTimeProperty(auto_now_add=True)
    ip_address = db.StringProperty()

class MainPage(webapp.RequestHandler):
    def get(self):

        # obtain ip address
        ip = self.request.remote_addr

        # create a new Log record
        log = Log()

        # assign ip address to the ip_address field
        log.ip_address = ip

        # no need to set access_time because 
        # of the auto_now_add=True setting defined in the Log model

        # save to the datastore

        # output 
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.out.write('Logged your visit from ip address %s' % ip)

class LogPage(webapp.RequestHandler):
    def get(self):
        logs = Log.all()

        self.response.headers['Content-Type'] = 'text/plain'
        self.response.out.write('Ip addresses: ')
        for log in logs:
            self.response.out.write(log.ip_address + ',')

application = webapp.WSGIApplication([("https://stackoverflow.com/", MainPage), ('/logs', LogPage)],

def main():

if __name__ == "__main__":

Try with:


or with the Request Class variable:

class MyRequestHandler(webapp.RequestHandler):
    def get(self):
        ip = self.request.remote_addr


works for me, I use appengine python3.7 standard env.
