IPv6 (Internet Protocol version 6) is the latest version of the Internet Protocol used to identify and communicate with devices and servers connected to the internet.
Every device connected to the internet requires an IP address to communicate with other devices. IPv6 was developed to replace IPv4, the older addressing system, because the number of available IPv4 addresses is limited.
IPv6 provides a significantly larger address space, improved networking efficiency, and modern capabilities designed to support the continued growth of the internet.
Why Was IPv6 Created?
The original IPv4 system was designed when the internet was much smaller. Over time, the number of internet-connected devices increased significantly, including:
- Websites.
- Smartphones.
- Computers.
- Servers.
- IoT devices.
- Cloud infrastructure.
Because IPv4 addresses are limited, IPv6 was introduced to provide a vastly larger pool of unique IP addresses and accommodate the continued expansion of the internet.
What Is the Difference Between IPv4 and IPv6?
The primary difference between IPv4 and IPv6 is the size of their address space.
IPv4
IPv4 uses a 32-bit address format and provides approximately 4.3 billion unique IP addresses.
Example:
192.168.1.1
IPv6
IPv6 uses a 128-bit address format, providing an extremely large number of unique IP addresses.
Example:
2001:0db8:85a3:0000:0000:8a2e:0370:7334
The much larger IPv6 address space allows the internet to continue expanding without the same address limitations associated with IPv4.
What Are the Benefits of IPv6?
IPv6 provides several advantages, including:
- A significantly larger number of available IP addresses.
- More efficient address allocation.
- Improved routing efficiency.
- Better support for modern internet-connected devices.
- Reduced reliance on Network Address Translation (NAT).
- Improved support for future internet growth.
Does IPv6 Improve Website Speed?
IPv6 does not automatically make a website faster.
Website performance depends on several factors, including:
- Hosting infrastructure.
- Server performance.
- Website optimisation.
- Caching.
- CDN usage.
- Database performance.
- Application configuration.
- Network conditions.
However, IPv6 can provide more efficient connectivity in networks where it is properly supported and configured.
Do I Need IPv6 for My Website?
Most websites can continue to operate successfully using IPv4. However, supporting IPv6 can improve compatibility with modern networks and internet service providers that use IPv6.
IPv6 support can be particularly beneficial for:
- Businesses serving visitors globally.
- Modern web applications.
- Large-scale online platforms.
- Cloud-based infrastructure.
- Hosting environments designed for future network requirements.
You do not necessarily need to configure IPv6 manually if your hosting provider already provides IPv6 support and manages the required network configuration.
Does SIRSTEVEHQ Support IPv6?
IPv6 availability depends on the hosting platform, server configuration, and data centre environment.
SIRSTEVEHQ continues to improve its infrastructure and adopt modern internet technologies. If you need to confirm whether IPv6 is available for your specific hosting plan or server, please contact our Support Team through a support ticket.
Can I Use IPv6 With My Domain Name?
Yes.
A domain can be configured to use an IPv6 address by adding an AAAA DNS record.
For example:
- A record → Points a domain or hostname to an IPv4 address.
- AAAA record → Points a domain or hostname to an IPv6 address.
If your hosting service supports IPv6, the appropriate DNS records can be configured to point your domain to the server's IPv6 address.
Does IPv6 Replace IPv4 Completely?
No.
IPv6 has not completely replaced IPv4. Both protocols currently operate alongside each other through technologies such as dual-stack networking, where systems support both IPv4 and IPv6.
The transition from IPv4 to IPv6 is ongoing, and many websites, servers, networks, and internet service providers continue to support both protocols.
Need Help Configuring IPv6?
If you need assistance with IPv6, DNS records, or checking whether your hosting plan supports IPv6, please open a support ticket through your Client Area.
When contacting us, please include:
- Your domain name.
- Your hosting plan or service.
- The IPv6 configuration you need.
- Any error messages or issues you are experiencing.
Our Support Team will review your setup and guide you through the appropriate configuration.
