Dedicated ISP Proxies Quick Start Guide

Dedicated ISP Proxies (DISP) are a premium proxy solution built for scenarios where consistency, performance, and trust are critical. They provide fully dedicated, static IP addresses sourced from top-tier ISP providers (premium ASNs). This guarantees predictable behavior, unlimited-duration sessions, and reliable access even on the most challenging targets.

Plus, unlike with regular ISP proxies, you can also explicitly choose your preferred ISP provider during setup, giving you maximum control over IP reputation and performance from the get-go.

This quick start guide will show you all the basics on how to set up and start using Oxylabs Dedicated ISP Proxies: from accessing your proxies to making your first request and understanding common responses.

Setting up Self-Service Dedicated ISP Proxies

1. Register and purchase IPs

First, log in to your Oxylabs dashboard (or create a free account) and choose a Dedicated ISP proxy plan. Then, if needed, allocate your IPs to desired locations and assign premium ASNs. If no locations or ASNs are selected, IPs will be selected randomly. Once you’re happy with your setup, complete the transaction.

Note: Dedicated ISP proxies are provided as static IPs mapped to specific ports. Each proxy remains assigned to you for the duration of your subscription.

2. Set up a proxy user

Next, you need to create your proxy credentials. Set a username and password, then click Create proxy user. These credentials will be used to authenticate your requests when using your Dedicated ISP proxies.

Alternatively, if you do not create a proxy user right away, you can create one in your dashboard’s Dedicated ISP Proxies section by choosing the Users tab and clicking New user.

3. Run a request

Once credentials are ready, you can test your Dedicated ISP proxies by sending a simple cURL request through a terminal or any appropriate environment. The example request below will check the outgoing IP address of your first Dedicated ISP proxy IP:

curl -x https://disp.oxylabs.io:8001 -U user-USERNAME:PASSWORD https://ip.oxylabs.io/location

Here, the request consists of:

Host: disp.oxylabs.io
Port: 8001 (the first IP on your proxy list)
Credentials: user-USERNAME:PASSWORD (“user-” prefix is mandatory, replace placeholders with your credentials)
Request target: https://ip.oxylabs.io/location

If the request is successful, the response will display the IP address linked to the selected port. Because the IP is fixed, the same address will be used across repeated or long-running sessions.

You can use the same technique to test all your IPs by incrementing the ports (8002, 8003, etc.). To find the full list of your IPs and their ports, go to the My Products section in the Oxylabs dashboard, click on Dedicated ISP Proxies, and select Proxy List.

What's included in a proxy list?

List column	Description
Entry point	The gateway to connect to your proxies
Port	The port number that allows you to access a specific proxy from your list
Country	The geographic location of your proxies
ISP (ASN)	The provider and ASN identifier of your proxy
Assigned IP	A specific proxy IP assigned to the chosen port

You can export this list in CSV or JSON format directly from the dashboard for easier integrations.

Location & ISP Info

Dedicated ISP proxies are tied to fixed locations. To access an IP with a specific location, you do not need to provide any additional parameters. Simply send a request to the port associated with the IP address of the desired location.

However, if you ever need to verify the network provider of your ISP IPs and have the most accurate, real-time data, we recommend checking the ISP provider and ASN data in the RIPEstat database.

Supported protocols

Dedicated ISP proxies support multiple connection protocols:

HTTP
HTTPS
SOCKS5 (TCP and UDP)

To set the desired protocol, such as HTTPS, add https:// before the entry point, like in the following example:

curl -x https://disp.oxylabs.io:8001 -U user-USERNAME:PASSWORD https://ip.oxylabs.io/location

Here’s a code example with the SOCKS5 protocol:

curl -x socks5h://user-USERNAME:PASSWORD@disp.oxylabs.io:8001 https://ip.oxylabs.io/location

Note: Make sure that the libraries or third-party tools you intend to use are compatible with HTTPS and SOCKS5 protocols.

Response codes

If a request fails, the Dedicated ISP proxies may return one of the following response codes that explain the reasons for failure:

Response code	Error message	Description
400	Bad Request	The request did not specify a host to connect to, or if there was a general error in parsing the HTTP request. Ensure that the request is correctly formed, including the URL, and try again.
404	Not Found	The domain you specified in your request could not be found. This can often occur due to the misspelling of the target URL or other niche factors.
407	Proxy Authentication Required	The request lacks proxy authentication information, or the username or password is invalid. Include the Proxy-Authorization header in your request, verify that your username and password are correct, then try again.
500	Internal Server Error	The proxy server has encountered an internal error. Retry the request at a later time.
503	Service Unavailable	Failed to connect to the target server. DNS failed to resolve the target server address.
504	Gateway Timeout	A proxy server timed out, waiting for a response from the target server. It usually takes about 60 seconds.
522	Timeout	The proxy server did not get a response from the upstream server in time. Retry the request.

Important: When sending a request, be sure to specify the port number rather than the IP address.

Usage statistics

You can monitor traffic usage, request counts, and error rates directly in the Oxylabs dashboard. Because Dedicated ISP Proxies are assigned only to you and include unlimited bandwidth under a fair usage policy, performance is affected only by your own workload.

Additionally, there is an option to filter the statistics and view metrics for a specific time period. Here’s what the dashboard looks like:

You can also filter the information by targets, IPs, or countries. Additionally, you may refine the data further by date range, IP, subnet, target, or user. On this page, you will also be able to see the number of errors you’ve received.
