# incidrlist

**Syntax**

```programlisting
incidrlist(<IP_address list>, <CIDR_range>)
```

**Description**

The `incidrlist()` function accepts a string containing a comma-separated list of IP addresses, and an IP range using CIDR notation, and returns `true` if any of the addresses are in the range.

**Examples**

Return `true` if any of the IP addresses fall within the specified IP range. Note that the input type is a comma-separated list of IP addresses, and not an array of IP addresses.

```programlisting
alter inrange = incidrlist("192.168.10.16,192.168.10.3", 
                           "192.168.10.0/24")
| fields inrange
| limit 1
      
```

If you want to evaluate a true array of IP addresses, convert the array to a comma-separated list using [arraystring()](/cortex-xdr-3.x/cortex-xdr-3.x-documentation/cortex-xdr-xql/functions/arraystring.md). For example, using the `pan_ngfw_traffic_raw` dataset:

```programlisting
dataset = panw_ngfw_traffic_raw 
| filter dest_ip != null
| comp values(dest_ip) as dips by source_ip,action
| alter dips = arraystring(dips, ", ")
| alter inrange = incidrlist(dips, "192.168.10.0/24")
| fields source_ip, action, dips, inrange
| limit 100
```

## 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://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/cortex-xdr-xql/functions/incidrlist.md?ask=<question>&goal=<endgoal>
```

`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.
