Full nodes for the Mainnet environment process SuiNS names without additional configuration. The Mysten Labs public nodes for Testnet also resolve SuiNS names. 

Mysten Labs public nodes:

- Mainnet: https://fullnode.mainnet.sui.io:443
- Testnet: https://fullnode.testnet.sui.io:443
- Devnet: https://fullnode.devnet.sui.io:443
    - SuiNS name resolution unavailable for Devnet.

## Full node configuration

Full node configuration is necessary for nodes to resolve SuiNS names in the Testnet environment. Devnet is not supported because of its frequent updates.
