Investigating the potential of the “supernet” idea would interconnect and enable communication across hitherto inaccessible networks by fusing them into a single, unified whole.
Like the human population, the internet is full of disparate parts that may be combined to form a whole. The allocation of IP addresses pre-supernet was done in blocks according to social status. IPv4 addresses were scarce since Class A only gave 127 network blocks, whereas Class B supported 63,534 hosts and 15,384 networks. In 1993, the IETF created the supernet to improve network scalability beyond the capabilities of the classful addressing scheme.
What Exactly Is a Supernet?
Supernet eliminates the need for centralized intermediaries while facilitating communication across disparate networks. It consolidates several networks into a unified system with a single Internet access point. The master router coordinates the system’s other routers. Protocols for inter-chain communication, atomic inter-chain trading, and side-chains are essential to the functioning of a supernet. Cross-chain communication is made more accessible with Polkadot and Cosmos, and decentralized asset trading is made possible with atomic swaps. The Supernet technology makes the transfer of assets between the main blockchain and the sidechain possible.
How Does Supernet Work?
Supernet efficiently decreases routing table space by grouping routes into smaller networks. To do this, it employs several different technologies and protocols, including cross-chain communication protocols, atomic swaps, and sidechains.
Supernetting vs Subnetting
Subnetting breaks up a single network into smaller networks, whereas supernetting combines many networks into a bigger supernet or metanet. With router summarization, supernetting routes that share the same network prefix are collapsed into a single routing entry. While supernetting adds bits to host identifiers, subnetting adds them to network identifiers.
Making a Supernet
You may use third-party solutions like SolarWinds IP Address Management Software or a supernet calculator to deal with the extra work of constructing a supernet. Check that the suggested networks are in order, have the same size, and are a power of two. In the first IP block, the value of the non-common octet must be zero or a multiple of the networks being combined. Once potential target networks have been located, cross-chain communication protocols and atomic swaps can be implemented. Create auxiliary chains and run infrastructure tests before launching the supernetwork to find and fix any problems.
Benefits and Drawbacks
The advantages of supernetting, a cutting-edge technology, are many. Its interoperability may be used to efficiently manage assets and facilitate communication across different blockchain networks. This is made feasible through cross-chain and side-chain transactions, which boost transaction speeds and provide value for users. By eliminating the need for trusted third parties, supernetting allows distributed applications and platforms to manage many blockchains. Additionally, the efficiency of IP addresses is improved by supernetting, which helps to conserve IP addresses and reduce the number of routes in the routing table.
In addition to reducing the administrative burden, consolidating several networks into a single supernet also offers improved network security. Data may be sent more quickly and with fewer disruptions thanks to supernetting’s impact on network traffic.
Despite these advantages, supernetting has its drawbacks, which must be considered. The intricate procedure calls for professionals with experience working with blockchain networks and advanced computing equipment. The price of software, hardware, and other resources might make supernetting prohibitive. However, security risks are also a consideration, as combining disparate networks into one supernet can introduce serious vulnerabilities. In addition, not every network hardware or software is CIDR-compatible, which might make it challenging to combine incompatible networks into a single “supernet.”
By creating a decentralized infrastructure enabling different blockchain networks to connect, supernetting removes the need for centralized intermediaries. Internet traffic is also decreased as a result. While supernetting is a valuable tool for many situations, it does have some restrictions.
