User question:
user: I'm doing an analysis on our network traffic and need to identify the zip codes for several IP addresses that have come up in the logs. Could you find the zip codes for '192.168.1.1', '172.16.254.1', '10.0.0.1', and '203.0.113.0'? It would really help to understand the potential sources of the traffic.

name: get_zipcode_by_ip_address
description: Finds the zipcode of an IP address.
parameters: type: dict
properties: ip_address: type: string
