User question:
user: During my investigation into a recent security breach, I've pinpointed a suspicious IP address that could be the source of the attack. The address is 192.168.1.1. To narrow down the physical location of the potential hacker, I need to find out the zipcode associated with this IP. Can you provide me with that information?

name: get_zipcode_by_ip_address
description: Finds the zipcode of an IP address.
parameters: type: dict
properties: ip_address: type: string
description: The IP address to find the location of.
required: ip_address

Ground-truth function call(s):
get_zipcode_by_ip_address(ip_address="192.168.1.1")
