IPv6 adoption is accelerating as IPv4 addresses become scarce. Understanding how IPv6 affects your hosting helps ensure your site remains accessible as the internet transitions to the new protocol.
What is IPv6?
IPv6 (Internet Protocol version 6) is the successor to IPv4, providing:
- Vastly more addresses – 340 undecillion vs IPv4's 4.3 billion
- Improved performance – More efficient routing
- Better security – Built-in IPSec support
- Simplified configuration – Auto-configuration features
Why IPv6 adoption matters
IPv4 address exhaustion
IPv4 addresses are running out globally, making IPv6 essential for new devices and services.
Mobile networks
Many mobile carriers primarily use IPv6, so sites without IPv6 support may be slower or inaccessible to mobile users.
Future-proofing
IPv6 is the future of the internet. Early adoption ensures your site remains accessible as more networks transition.
How IPv6 affects hosting
1. Dual-stack hosting
Most modern hosting supports both IPv4 and IPv6 simultaneously (dual-stack), ensuring compatibility with all visitors.
2. DNS configuration
IPv6 requires AAAA DNS records in addition to traditional A records. Proper DNS setup ensures IPv6 traffic reaches your site.
3. Performance benefits
IPv6 can offer better performance due to more efficient routing, though the difference is often minimal in practice.
Checking IPv6 support
- Test your site at ipv6-test.com
- Check DNS records for AAAA entries
- Verify hosting provider supports IPv6
- Test from IPv6-only networks
Transitioning to IPv6
- Verify hosting support – Ensure your provider offers IPv6
- Update DNS – Add AAAA records for your domain
- Test connectivity – Verify IPv6 access works
- Monitor performance – Ensure no negative impact
