# Proxy parameters GoProxies Shared DataCenter Proxies provide access to over 160 different locations and support country, city, and state targeting. ### Country, City, State mapping We currently use ip2location.com and ipinfo.io databases to assign exit values of `country`, `city` and `state` to our nodes. Other public databases might show different locations due to database differences. If location mismatches cannot occur, please first ensure the IP assigned by the proxy matches the target website's database location. If you have any additional questions, please contact your account manager or our support team at . --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
