IPv4 is an address format, not a proxy quality tier. A dotted-decimal exit can come from a datacenter, an ISP allocation, or a rotating residential device; choosing IPv4 alone says nothing about sharing, persistence, or target acceptance.
Start with your application’s compatibility requirement, then choose the origin and allocation of the exit. These providers document IPv4 services, but a gateway hostname or an IPv4 whitelist requirement alone would not prove that every product uses an IPv4 exit.

Detailed Provider Reviews
1) Webshare
Best for: Proxy-list integrations for IPv4-oriented clients
Webshare documents IPv4 addressing and provides a proxy-list API for clients that consume address-and-port entries. Choose the allocation tier separately: private can be limited-sharing, and dedicated is the exclusive option. Official product documentation.
Key Features
- Webshare documents IPv4 addressing across its proxy products.
- HTTP and SOCKS5 support enables common client formats.
- Datacenter and static ISP products offer different exit origins.
What We Like
- List-based deployment suits scripts expecting explicit connection entries.
- Allocation tiers allow a separate sharing decision.
What We Don’t Like
- Keep downloaded lists synchronized after replacements.
- An IPv4 connection entry does not guarantee target acceptance.
2) Oxylabs
Best for: Residential and datacenter IPv4 choices
Oxylabs explicitly markets IPv4 residential and datacenter proxies. Its integration guides and datacenter port mapping are useful when legacy client compatibility must coexist with either rotating collection or assigned exits. Official product documentation. Setup and allocation details.
Key Features
- IPv4 residential service offers rotating exits.
- IPv4 datacenter products provide a server-hosted alternative.
- Datacenter integration examples use authenticated requests.
What We Like
- Explicit IPv4 product documentation supports compatibility checks.
- Different origins suit different target policies.
What We Don’t Like
- Rotating residential exits do not provide permanent identity.
- Select IPv4 deliberately where a product also supports IPv6.
3) Decodo
Best for: IPv4 routing with access controls
Decodo’s IPv4 offering sits alongside shared and dedicated datacenter service. User:pass authentication and documented IPv4 whitelists give teams a concrete setup path, but the whitelist format should not be mistaken for an exit guarantee on unrelated products. Official product documentation. Setup and allocation details.
Key Features
- The IPv4 product page documents IPv4 proxy availability.
- Datacenter access supports credentials or whitelisting.
- Datacenter plans distinguish shared from dedicated IPs.
What We Like
- Dedicated IPv4 documentation makes the compatibility requirement explicit.
- Separate authentication options accommodate changing or fixed client addresses.
What We Don’t Like
- IPv4 support does not imply exclusive allocation.
- Traffic charging depends on the selected network and plan.
4) Bright Data
Best for: IPv4 projects spanning multiple network types
Bright Data provides an IPv4 service page and a zone-based integration model. Datacenter and ISP allocation modes let a team retain compatible exits while deciding independently whether it needs a shared pool or leased addresses. Official product documentation. Setup and allocation details.
Key Features
- IPv4 proxies are documented as an available service.
- Datacenter and ISP modes include shared and dedicated allocations.
- The Postman guide shows authenticated proxy configuration and exit checks.
What We Like
- Zones organize different integration requirements.
- Official exit-check instructions help validate application routing.
What We Don’t Like
- Confirm the required exit family on the exact purchased zone.
- Zone configuration and allocation introduce more setup decisions.
5) Thordata
Best for: Geographically targeted rotating IPv4 collection
Thordata’s IPv4 product is a rotating residential option with location targeting and dashboard controls. It suits authorized regional public-data collection rather than an application requiring one permanent dedicated address. Official product documentation.
Key Features
- Residential IPv4 exits rotate through the provider pool.
- Country, state, city, and ASN targeting refine selection.
- Dashboard tools track usage and manage subaccounts.
What We Like
- Regional controls support location-specific data collection.
- Subaccounts help separate project usage.
What We Don’t Like
- Rotating exits may interrupt workflows tied to one IP.
- Pool availability is not a guarantee of a particular city IP.
How we evaluated IPv4 compatibility
We compared explicit IPv4 documentation, exit origin, authentication, allocation, and integration controls; no live compatibility or speed tests were performed. The selection serves applications needing IPv4 exits for authorized browsing or data collection. Missing exit-family confirmation and unclear persistence or sharing rules reduced suitability.
- Require explicit IPv4 exit support.
- Separate residential origin from address version.
- Check allocation and rotation rules.
Verify the exit rather than just the gateway
A hostname can resolve differently from the exit used to reach a website. Validate the address seen by an IP-check endpoint from inside your actual client, without treating that one successful request as proof of universal compatibility.
- Configure the documented hostname, port, and credentials.
- Check the observed exit address.
- Repeat checks after reconnecting.
- Test the intended target with a small permitted request.
Choose persistence to match the application
IPv4 does not determine whether an address changes between requests. Use fixed allocated IPs for allowlists you control, and rotating exits only where changing identity does not undermine the authorized workflow.
- Use assigned exits for controlled allowlist integration.
- Avoid rotation during an authenticated session that expects one IP.
- Budget traffic separately from IP rental.
- Do not assume IPv4 inherently improves latency.
Related Proxy Guides
Compare the underlying networks in our guide to proxy types. For browser configuration, use our Chrome proxy settings guide and verify support in the application you intend to use.
- Choose the network type separately from the HTTP or SOCKS protocol.
- Confirm the selected plan’s locations and session limits before deployment.
- Test the authorized application rather than assuming every program uses system settings.
Verdict
Oxylabs and Decodo provide explicit IPv4 product choices, Webshare suits list-driven clients, and Bright Data suits zone-based configurations. Thordata is a practical candidate for rotating regional IPv4 collection. Confirm the exact exit family and persistence requirement before purchasing.
Frequently Asked Questions
Can an IPv4 proxy reach a website that only supports IPv6?
Only if the proxy infrastructure can connect to that destination over IPv6 or provides a suitable translation path. An IPv4 client-to-proxy connection alone does not establish that capability.
Do I need an IPv4 internet connection to use IPv4 exits?
Not necessarily, because your connection to the proxy and the proxy’s exit connection are separate. Your client must still be able to reach the provider gateway using a supported network path.
Will an IPv4 proxy work with older software?
It can work when the software supports the proxy protocol and authentication method. Address-family compatibility will not fix a client that lacks proxy support or rejects the provider’s credential format.
How are IPv4 proxy plans charged?
Plans may charge for traffic, allocated IPs, or both. Include renewal terms, traffic caps, and required allocation type when comparing costs.
Why does an IPv4 proxy fail even when the IP check works?
The target can reject an exit that an IP-check service accepts. Check the returned target status, geographic restrictions, destination rules, and application settings before changing providers.
Can I add IPv4 proxies to an Android app?
Yes, if the app or an appropriate routing client supports the proxy service. Android’s Wi-Fi proxy setting is not a universal SOCKS5 or per-app routing solution.
