Currently I have a function (view) that go over each URL to get the information, and update the DB.

It means response time does not matter for you and instead of doing it in the background (asynchronously), you are OK with doing it in the foreground if your response time is cut by 4 (using 4 sub-processes/threads). If that is the case you can simply put your sample code in your view. Like

from multiprocessing import Pool

def updateDB(ip):
     code goes here...

def my_view(request):
    pool = Pool(processes=4)              # process per core
    pool.map(updateDB, ip)
    return HttpResponse("SUCCESS")

But, if you want to do it asynchronously in the background then you should use Celery or follow one of @BasicWolf's suggestions.
