Domain Name
域名是互联网上标识网站与网络服务的字符型地址，通过DNS解析为IP地址，使用户无需记忆数字串即可访问目标服务。域名由顶级域、二级域与子域组成，遵循先申请先注册原则，由ICANN授权注册局管理、注册商提供服务。注册人获得的是有效期内使用权而非永久所有权，需按期续费，否则将经历宽限期、赎回期后被释放。域名管理的核心工作包括注册选型、DNS解析配置、实名认证与ICP备案、SSL证书绑定、安全防护（域名锁、DNSSEC、双重验证）及到期续费。域名是品牌数字资产的核心入口，被抢注或解析劫持会直接造成流量流失与业务中断。
Direct Answer
A domain name is a unique name on the internet used to identify and locate a website or network service, functioning as the 'street address' of a website. It consists of a string of characters, such as 'mangxu.com', allowing users to access the corresponding website by entering the domain name without needing to remember complex IP addresses. The Domain Name System (DNS) is responsible for resolving domain names into server IP addresses, enabling network access. Domain names are typically composed of multiple levels, including top-level domains (e.g., .com, .cn), second-level domains (e.g., mangxu), and subdomains (e.g., www). Domain registration must be conducted through a domain registrar, following a first-come, first-served principle, and requires periodic renewal to maintain ownership. Domain names are not only technical identifiers but also brand assets; proper domain selection and management are crucial for website operations, search engine optimization (SEO), and user trust.

FAQ
- What is a domain name? What is the difference between it and an IP address?
- A domain name is an easy-to-remember name used to identify a website or service on the internet, such as "mangxu.com." An IP address is a numerical identifier for a network device, like "192.168.1.1." Domain names are resolved to IP addresses through DNS, allowing users to access websites without memorizing numbers.
- How to choose a suitable domain name?
- When choosing a domain name, consider the following factors: short and easy to remember, include a brand or keyword, use common top-level domains (such as .com, .cn), avoid hyphens and numbers, and check for trademark conflicts. It is also recommended to register multiple related suffixes to protect the brand.
- What needs to be done after registering a domain name?
- After registering a domain name, you need to configure DNS resolution settings to point the domain to the website server IP; set up WHOIS information (privacy protection can be enabled); renew regularly to prevent expiration; and set a domain lock to prevent unauthorized transfers.
- Can a domain name be recovered after it expires?
- After a domain name expires, there is usually a grace period of about 30 days for renewal, followed by a redemption period (approximately 30 days) requiring a high redemption fee. Beyond the redemption period, the domain will be released and made available for registration again. It is recommended to enable auto-renewal.
- What is domain name resolution? How to set it up?
- Domain name resolution is the process of converting a domain name into an IP address, completed by DNS servers. When setting it up, you need to add A records (pointing to IPv4 addresses), CNAME records (aliases), or MX records (mail servers) in the domain management backend.
