Oxylabs Proxies

Proxy Types Overview

| Type | Host | Port | Best For |

|------|------|------|----------|

| Residential | pr.oxylabs.io | 7777 | High anonymity, geo-targeting |

| Mobile | pr.oxylabs.io | 7777 | Mobile-specific content, highest trust |

| Datacenter (shared) | dc.oxylabs.io | 8000 rotation / 8001+ assigned/static | Speed, high volume |

| ISP (shared) | isp.oxylabs.io | 8000 rotation / 8001+ assigned/static | Speed + anonymity balance |

| Dedicated Datacenter | ddc.oxylabs.io | 8000 rotation / 8001+ assigned/static | Owned IPs, port-based access |

| Dedicated ISP | disp.oxylabs.io | 8000 rotation / 8001+ assigned/static | Owned ISP IPs, ASN locked |

Residential/Mobile use pr.oxylabs.io:7777 with username session parameters. Datacenter/ISP and Dedicated self-service products use proxy-list ports starting at 8001 for assigned/static IPs and 8000 for automatic rotation.

Environment Variables

Use credentials for the specific proxy product family:

| Product family | Variables | Username prefix |

|----------------|-----------|-----------------|

| Residential, Mobile | OXY_RES_USERNAME, OXY_RES_PASSWORD | customer- |

| Datacenter, ISP, Dedicated Datacenter, Dedicated ISP | OXY_DC_USERNAME, OXY_DC_PASSWORD | user- for self-service/shared |

Authentication Format

customer-USERNAME:PASSWORD    # Residential, Mobile
user-USERNAME:PASSWORD          # Shared Datacenter, Shared ISP

Dedicated proxy auth (Self-Service vs Enterprise) is in [dedicated-datacenter.md](dedicated-datacenter.md) and [dedicated-isp.md](dedicated-isp.md).

Use separate credentials for Residential/Mobile (OXY_RES_USERNAME, OXY_RES_PASSWORD) and Datacenter/ISP (OXY_DC_USERNAME, OXY_DC_PASSWORD).

With parameters:

customer-USERNAME-cc-US-city-new_york-sessid-abc123:PASSWORD

Quick Start

Residential/Mobile proxy:

curl -x "pr.oxylabs.io:7777" \
  -U "customer-$OXY_RES_USERNAME:$OXY_RES_PASSWORD" \
  "https://ip.oxylabs.io/location"

Datacenter proxy:

curl -x "dc.oxylabs.io:8000" \
  -U "user-$OXY_DC_USERNAME:$OXY_DC_PASSWORD" \
  "https://ip.oxylabs.io/location"

ISP proxy:

curl -x "isp.oxylabs.io:8001" \
  -U "user-$OXY_DC_USERNAME:$OXY_DC_PASSWORD" \
  "https://ip.oxylabs.io/location"

For Datacenter, ISP, Dedicated Datacenter, and Dedicated ISP proxies, use dashboard proxy-list ports starting at 8001 for assigned/static IPs; the first listed IP uses 8001. Switch to port 8000 only when the task calls for automatic rotation.

Geo-Targeting Parameters

For Residential/Mobile, append username parameters with hyphens unless noted:

| Parameter | Format | Example |

|-----------|--------|---------|

| cc | ISO 3166-1 alpha-2 | -cc-US, -cc-DE, -cc-GB |

| city | English, underscores for spaces | -city-new_york, -city-los_angeles |

| st | US states with us_ prefix | -st-us_california, -st-us_texas |

| postalcode | 5-digit US ZIP, pair with cc-US | -cc-US-postalcode-90210 |

| ASN | Residential/Mobile carrier ASN | -ASN-21928 |

| X-Oxylabs-Geolocation | Proxy header lat:lon;radius_miles | 49.9235:-97.0811;10 |

ZIP targeting is US-only. Coordinate radius cannot be lower than 10 miles. If both country and ASN are used, country applies.

Example with geo-targeting:

curl -x "pr.oxylabs.io:7777" \
  -U "customer-$OXY_RES_USERNAME-cc-US-city-new_york:$OXY_RES_PASSWORD" \
  "https://ip.oxylabs.io/location"

For Shared Datacenter/ISP country rotation, use -country-US with user- credentials on the rotation port.

Session Control

| Parameter | Description | Notes |

|-----------|-------------|-------|

| sessid | Keep the same IP across requests | Standard session is 10 minutes or up to 60s of inactivity |

| sessid_oneip | Bind the session to one exact exit node | Returns 502 if that IP becomes unavailable |

| sesstime | Set session duration in minutes with sessid or sessid_oneip | Residential backconnect supports up to 1440 minutes; some entry modes cap lower |

Sticky session example:

curl -x "pr.oxylabs.io:7777" \
  -U "customer-$OXY_RES_USERNAME-cc-US-sessid-mysession123:$OXY_RES_PASSWORD" \
  "https://example.com"

Timed session (5 minutes):

curl -x "pr.oxylabs.io:7777" \
  -U "customer-$OXY_RES_USERNAME-sessid-abc123-sesstime-5:$OXY_RES_PASSWORD" \
  "https://example.com"

Choosing the Right Proxy Type

| Need | Recommended |

|------|-------------|

| Highest anonymity | Residential |

| Mobile app content | Mobile |

| Speed & volume | Datacenter |

| Speed + anonymity | ISP |

| Owned dedicated IPs | Dedicated Datacenter or Dedicated ISP |

| Geo-restricted content | Residential/Mobile with cc/city/postalcode, or DC/ISP by country/assigned port where suitable |

Default Behavior

• Without parameters: random IP for each request
• Residential/Mobile share the same endpoint but different IP pools
• Sessions auto-expire and get new IPs
