Embracing the Future: Enabling IPv6 Support

IPv6 is the latest version of the Internet Protocol (IP) that provides unique 128-bit addresses for devices on networks. Its vast address space of 3.4×10^38 supports the increasing demand for internet-connected devices, overcoming the limitations of IPv4's address space, which couldn't meet the growing requirements of the internet.

IPv4 vs IPv6

Larger Address Space

IPv6 boasts a substantial advantage over IPv4 with its extensive address space of 128 bits (340 undecillion addresses!). The designers didn't aim for geographical saturation, but the longer addresses streamline allocation, efficient route aggregation, and special addressing features. IPv4's complex CIDR methods for the limited address space are surpassed by IPv6's standard subnet size of 264 addresses—four billion times larger than the whole IPv4 space.

Multicasting

IPv6 embraces multicasting as a fundamental aspect, unlike IPv4, where it's an optional feature. IPv6 multicast addresses share some traits with IPv4 multicast, but they eliminate the need for certain protocols, introducing improvements. The former does not implement traditional IP broadcast, using the link-local all nodes multicast group (ff02::1) instead. This new version also simplifies inter-domain solutions by embedding rendezvous point addresses in multicast group addresses.

Stateless Address Autoconfiguration (SLAAC)

IPv6 hosts achieve automatic configuration by self-generating link-local addresses, resolving conflicts, and obtaining network prefixes from routers via advertisements. Routers can be statelessly configured through a renumbering protocol. For additional addresses, hosts may use DHCPv6 or manual setup. IPv6 emphasises the end-to-end principle, rendering network address translation obsolete and allowing every device to have globally unique IP addresses for direct global accessibility.

Other Benefits

Unlike mobile IPv4, mobile IPv6 eliminates triangular routing, ensuring efficiency comparable to native IPv6. IPv6 routers enable seamless movement of entire subnets to new connection points without requiring renumbering, offering enhanced flexibility and streamlined network management. IPv4 restricts payloads to 65,535 (216−1) octets. However, IPv6 allows jumbograms, packets exceeding this limit, reaching sizes up to 4,294,967,295 (232−1) octets. Jumbograms, signified by the Jumbo Payload Option extension header, can enhance performance on high-MTU links, offering increased data capacity and efficiency.

How are Companies using IPv6?

Internet Connectivity

Many companies use IPv6 to provide internet connectivity to their internal networks and external-facing services. IPv6 enables them to handle the increasing number of devices connected to the internet.

Website Hosting

Companies host their websites using IPv6 to make them accessible to users with IPv6-enabled devices. This allows businesses to reach a broader audience and ensures compatibility with modern networks.

Cloud Services

Cloud service providers often offer IPv6 support, allowing companies to deploy applications and services in the cloud with IPv6 addresses. This facilitates seamless communication between cloud-based resources and clients with IPv6-capable devices.

IoT (Internet of Things)

As the number of IoT devices grows, IPv6 is becoming essential to provide unique IP addresses for each connected device. IPv6's vast address space ensures scalability and flexibility for managing large-scale IoT deployments.

Network Infrastructure

Companies are updating their network infrastructure to support IPv6, including switches, routers, firewalls, and load balancers. This ensures end-to-end IPv6 connectivity across their networks.

Mobile Networks

Mobile carriers and providers are increasingly adopting IPv6 to accommodate the surge in mobile devices and to support the transition to 5G networks, which often rely on IPv6.

Internal Networks

Companies use IPv6 within their internal networks to support devices and services that are IPv6-enabled. This includes internal communication, server-to-server communication, and other network services.

Security Enhancements

IPv6 provides built-in security features, such as IPsec (Internet Protocol Security). Companies are utilising these security features to enhance the protection of their data and communications.

Setting up IPv6

Thinking of using an IPv6 tracker? Be it a tracker or any other IPv6 supported device, Roadcast has a solution for you! We make sure your server's firewall and security settings are updated to handle IPv6 traffic. This includes allowing incoming and outgoing IPv6 packets on specific ports, as well as implementing any necessary security measures to protect against IPv6-specific threats. We ensure that your server's DNS settings are correctly configured for IPv6. This involves adding AAAA records to your domain's DNS zone, which associate IPv6 addresses with domain names. Set up monitoring and logging for IPv6 traffic on your server. This will help you keep track of any potential issues and ensure smooth operation.

Your server's network routing needs to be properly configured to handle IPv6 traffic. This includes updating routing tables and configuring any necessary routing protocols for IPv6. Before deploying IPv6 support to production, we thoroughly test and troubleshoot IPv6 connectivity and functionality on your server. This can be done in a controlled environment or using IPv6 testing tools available online.

Still pondering over the IPv4 vs IPv6 debate? Embracing IPv6 unlocks a world of possibilities for our interconnected future. The adoption of IPv6 has been an ongoing process and this transition from IPv4 to IPv6 is crucial for the continued growth of the internet and to ensure a stable and scalable network for future innovations and technologies. Our cutting-edge technology Bolt enables seamless support for IoT devices that use IPv4 or exclusively only use IPv6.
