# Datacenter Proxies

## User credentials

To start using Oxylabs' Datacenter Proxies, you must first go to [**Oxylabs' dashboard**](https://dashboard.oxylabs.io/en/) and purchase a plan that fits your needs.\
After, you will be guided to create your proxy user. Proxy user credentials is your access to Datacenter Proxies. 

## Making requests

After you create a proxy user, you will be prompted to a pop up with your first test request to receive a random IP. \
Copy it and change the `USERNAME` and `PASSWORD` parameters to your proxy credentials: 

```bash
curl -x dc.oxylabs.io:8000 -U "user-USERNAME:PASSWORD" https://ip.oxylabs.io/location 
```

To get **a specific proxy** while making requests, refer to [**IP Control** ](https://developers.oxylabs.io/~/changes/1231/proxies/datacenter-proxies/ip-control)page.

{% hint style="info" %}
Use [**ip.oxylabs.io/location**](https://ip.oxylabs.io/location) to check the parameters of your IPs — this domain delivers information from four geolocation databases: MaxMind, IP2Location, DB-IP, and IPinfo.io. The parameters include IP address, provider, country, city, ZIP code, ASN, organization name, time zone, and meta (when disclosed by database).
