# 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.
