I don't see what that will accomplish. Of what value is the hostname vs the IP address? Many servers have proper reverse entries in DNS to map IP addresses back to host names. Furthermore a packet trace can show exactly what the HTTP request was, and that doesn't matter whether you do IP address or hostname. As for whether the IP address changes often, depends on the server. Sometimes some web sites use a cluster of servers and each name lookup will give you a different IP address (round robin lookup). -- https://mail.python.org/mailman/listinfo/python-list
