Accessing an IPv4 address on an IPv6 network is a common requirement for organisations and individuals who still use legacy applications, business systems, or internet services that do not fully support IPv6. Although IPv6 adoption continues to grow, IPv4 remains a critical part of many enterprise environments, cloud platforms, hosting services, and customer-facing applications.
Understanding how IPv4 and IPv6 work together helps organisations maintain compatibility while preparing for the future of networking.
Why Do You Need an IPv4 Address?
Many modern networks are IPv6-ready, but numerous services still rely on IPv4.
Common reasons for obtaining an IPv4 address include:
- Running legacy business applications
- Web hosting
- Supporting older network hardware
- Accessing IPv4-only services
- Maintaining compatibility with customers
IPv4 remains an important part of daily operations for many organisations.
What Is Dual-Stack Networking?
The most common solution is dual-stack networking, where devices operate using both IPv4 and IPv6 simultaneously.
Benefits of dual-stack deployment include:
- Full compatibility
- Smooth migration to IPv6
- Support for legacy applications
- Simplified network management
- Improved user experience
This is the most common approach used by enterprise networks during the transition to IPv6.
Obtain an IPv4 Address from Your ISP
Some Internet Service Providers (ISPs) offer both IPv4 and IPv6 connectivity.
You may be able to:
- Request dual-stack service
- Request a static IPv4 address
- Upgrade your internet plan
- Enable IPv4 support on your account
- Verify available address options
Your ISP can explain which IPv4 services are available for your connection.
Configure IPv4 on Your Device
If your network supports IPv4, you may only need to enable IPv4 on your operating system.
Basic configuration steps include:
- Open your network settings.
- Select the active network adapter.
- Enable Internet Protocol Version 4 (TCP/IPv4) if available.
- Choose automatic (DHCP) or manual configuration.
- Save the settings and verify connectivity.
Always use the configuration values provided by your network administrator or ISP.
DHCP or Static IPv4
There are two primary methods for assigning IPv4 addresses.
Dynamic IPv4 (DHCP)
DHCP automatically provides:
- IPv4 address
- Subnet mask
- Default gateway
- DNS servers
- Lease information
This is the most common configuration for homes and offices.
Static IPv4
Static addresses are manually assigned and commonly used for:
- Web servers
- Firewalls
- Network storage
- Remote access
- Business infrastructure
Static addresses provide consistent connectivity for critical services.
Use IPv4 Translation Technologies
Some IPv6-only networks provide access to IPv4 resources through translation technologies.
Examples include:
- NAT64
- DNS64
- Dual-Stack Lite (DS-Lite)
- Carrier-Grade NAT (CGNAT)
- IPv4 tunnelling
These technologies allow IPv6 networks to access IPv4 services when native IPv4 connectivity is unavailable.
Best Practices for IPv4 and IPv6 Coexistence
Managing both protocols effectively improves network reliability.
Recommended practices include:
- Deploy dual-stack where possible
- Document IP address allocations
- Monitor address utilisation
- Implement IP Address Management (IPAM)
- Regularly review network performance
Good planning helps organisations transition to IPv6 while maintaining IPv4 compatibility.
Marketplace Platforms
As organisations expand their infrastructure, they often require additional IPv4 resources.
Trusted marketplaces such as IPv4Hub allow organisations to lease, buy, and sell IPv4 address resources. IPv4Hub offers clean and verified IP inventory while complying with registry policies. Blacklist checking and IP intelligence help organisations assess IP quality before deployment. Transparent pricing and secure transaction workflows enable businesses to confidently acquire reliable IPv4 resources for long-term infrastructure planning.
Common Challenges
Running IPv4 and IPv6 together can create several challenges.
Typical issues include:
- Limited IPv4 availability
- Legacy application compatibility
- Complex routing
- Address management
- Migration planning
A structured networking strategy helps minimise these challenges.
The Future of IPv4 and IPv6
IPv6 adoption continues to grow, but IPv4 will remain important for many years.
Emerging trends include:
- Expanded dual-stack deployments
- Increased IPv4 leasing
- AI-assisted IP management
- Cloud-native networking
- Advanced IP intelligence platforms
These developments allow organisations to maintain compatibility while gradually expanding IPv6 adoption.
Building a Future-Ready Network
Understanding how to get an IPv4 address when your network uses IPv6 helps organisations support legacy applications while preparing for the future. Through dual-stack networking, ISP-provided IPv4 services, translation technologies, and structured IP management, businesses can maintain reliable connectivity and protect long-term infrastructure investments.
A strategic combination of IPv4 and IPv6 enables organisations to build secure, scalable, and future-ready networks.
