# Parallel Networks
Most of the time, we describe the XRP Ledger as one collective, singular entity -- and that's mostly true. There is one production XRP Ledger peer-to-peer network, and all business that takes place on the XRP Ledger occurs within the production network.
There is one production XRP Ledger peer-to-peer network, and all business that takes place on the XRP Ledger occurs within the production network—the Mainnet.
However, sometimes you may want to do tests and experiments without interacting with the core network. That's why Ripple started the [Ripple Test Net](xrp-test-net-faucet.html), an "alternate universe" network, which can act as a testing ground for applications and the `rippled` server itself, without impacting the business operations of everyday XRP Ledger users. The Ripple Test Net (also known as the AltNet) has a separate supply of TestNet-only XRP, which Ripple [gives away for free](xrp-test-net-faucet.html) to parties interested in developing applications on the Test Net.
To help members of the XRPL community interact with XRPL technology without affecting anything on the Mainnet, Ripple hosts two alternative networks, or altnets: the Testnet and the Devnet. Here's a breakdown of all three networks:
**Caution:** Ripple makes no guarantees about the stability of the test network. It has been and continues to be used to test various properties of server configuration, network topology, and network performance.
| Network | Upgrade Cadence | Description |
|:--------|:----------------|:-------------------------------------------------|
| Mainnet | Stable releases | _The_ [XRP Ledger](xrp-ledger-overview.html), a decentralized cryptographic ledger powered by a network of peer-to-peer servers and the home of [XRP](xrp.html). |
| Testnet | Stable releases | An "alternate universe" network that acts as a testing ground for software built on the XRP Ledger, without impacting production XRP Ledger users and without risking real money. The [amendment status](known-amendments.html) of the Testnet is intended to closely mirror the Mainnet, although slight variations in timing may occur due to the unpredictable nature of decentralized systems. |
| Devnet | Beta releases | A preview of coming attractions, where unstable changes to the core XRP Ledger software may be tested out. Developers can use this altnet to interact with and learn about planned new XRPL features and amendments that are not yet enabled on the Mainnet. |
Testnet and Devnet each have their own separate supply of test XRP, which Ripple [gives away for free](xrp-testnet-faucet.html) to parties interested in experimenting with the XRP Ledger and developing applications and integrations. Test XRP does not have real-world value and is lost when the network is reset.
**Caution:** Ripple makes no guarantees about the stability of altnets. These networks have been and continue to be used to test various properties of server configuration, network topology, and network performance.
Over time, there may also be smaller, temporary test networks for specific purposes.
## Parallel Networks and Consensus
There is no `rippled` setting that defines which network it uses. Instead, it uses the consensus of validators it trusts to know which ledger to accept as the truth. When different consensus groups of `rippled` instances only trust other members of the same group, each group continues as a parallel network. Even if malicious or misbehaving computers connect to both networks, the consensus process overrides the confusion as long as the members of each network are not configured to trust members of another network in excess of their quorum settings.
Ripple operates the main servers in the Testnet and Devnet; you can also [connect your own `rippled` server to the Testnet](connect-your-rippled-to-the-xrp-test-net.html). The Testnet and Devnet do not use diverse, censorship-resistant sets of validators. This makes it possible for Ripple to reset the Testnet or Devnet on a regular basis.
