A key element of blockchain networks is the operation of bootstrap validator nodes: they help new nodes connect to the network and ensure initial synchronization. Therefore, it is of utmost importance that these nodes are reliably accessible from all environments.

To this end, we have now made our bootstrap validator nodes IPv6 compatible, so that validators whose ISPs only provide IPv6 addresses can connect seamlessly.

But what exactly does this mean?

On the Internet, we use IP addresses to identify devices. The older, still widely used system is IPv4, which uses addresses in the following format: 192.168.1.1. However, this system can only handle a limited number of addresses (about 4.3 billion), which has become a bottleneck with the ever-increasing number of devices.

In contrast, IPv6 is a more modern solution that uses much longer addresses (for example, 2001:0db8:…) and provides a practically inexhaustible amount of unique IP addresses. More and more service providers are switching to this system, and in fact, in some networks, only IPv6 is available. With our current development, we ensure that bootstrap nodes are accessible not only via IPv4, but also via IPv6. This is especially important for validators that operate in IPv6-only environments, since it was previously not possible for them to connect directly to bootstrap nodes. Overall, this step contributes to making our network more future-proof, flexible, and widely available – including in environments where only IPv6 is available.
