# Welcome to NeoNS Documentation ### What is NeoNS The Neo Name Service (NeoNS) is a distributed open naming system based on Neo blockchain. The main goal of NeoNS is to map names like `alice.neo` to other source identifiers such as N3 addresses, NeoFS shared link, IPV4 addresses, IPV6 addresses, and other metadata. NeoNS also has dot-separated hierarchical names called domains. The owner of a domain has full control of all its subdomains. Top-level domains, like `.neo`, are owned by the Neo Committee. Users can only register domains with the registered top-level domains, such as `alice.neo` instead of `alice.eth` if the top-level domain `.eth` is not registered yet. Once the domain `alice.neo` registered users can register any subdomains ended with it, for example, `hello.alice.neo`, and configure it with records. ### Quick Start NeoNS Mainnet Contract Hash: 0x50ac1c37690cc2cfc594472833cf57505d5f46de NeoNS Magnet N3T5 Hash (Recommended): 0x50ac1c37690cc2cfc594472833cf57505d5f46de The source code can be found \[here]\([non-native-contracts/src/NameService at master · neo-project/non-native-contracts · GitHub](https://github.com/neo-project/non-native-contracts/tree/master/src/NameService)). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
