# What is a 9dcc Subdomain? ## Intro - What is an ENS Name? The Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum blockchain. ENS’s job is to map human-readable names like ‘9dcc.eth’ to machine-readable identifiers such as an Ethereum address. In our case, 9dcc.eth resolves to our company Ethereum wallet: 0xF3936154fc93ecDA413de9f0A6E2cC20c56e**9dcc** **.eth** is the TLD(Top Level Domain) **9dcc.eth** is a 2LD(2nd Layer Domain) which our company owns ## So What Is A Subdomain? A Subdomain is a 3DL (3rd Layer Domain) or another layer that is controlled by the 2DL, in our case 9dcc. A common example of what this looks like in web2 of structure is the modern day email system. .com is a TLD gmail.com is a 2LD owned by Google YOURNAME @ gmail.com is a 3DL of gmail that is unique and associated to you but is controlled by Google \[you].9dcc.eth is a subdomain that can be created under our 9dcc.eth ENS domain that can associate to YOUR wallet and web3 persona. A subdomain is minted for you when you create a 9dcc Profile Account ## Why a 9dcc Subdomain? Owning a subdomain serves several purposes: * Owning a 9dcc subdomain is basically the modern-day equivalent of wearing a badge of honor. By purchasing a 9dcc product, we want to give owners the ability to associate their web3 persona with 9dcc * Owning a 9dcc subdomain enables us to do many things on and off chain to benefit holders such as connect to our loyalty Network Points system and more. --- # 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.
