# IP Whitelisting
IP Whitelisting is an added security measure, which allows clients to specify which IPs they want to permit to make API requests of their data. Should another IP make a request, the request will not be successful.
To whitelist an IP, simply select `Update` on your active token and then either add the permissioned IP addresses to the list of valid IPs. You can add your current IP using the `Add my IP` option. Users are not limited to how many IPs they can whitelist. Alternatively, IPs can be added when the token is first created.
To whitelist an IP, select 'Update'
Either add your current IP, or enter an IP manually
When finished, select `Save`. \
\
The list of a token's permitted IP addresses can be edited while the token remains active.

## 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.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.landytech.com/authentication/ip-whitelisting.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
