What is a domain name space?

Domain name space: The general term for "domain name + website space". Two things are usually used to make a website, one is a domain name and the other is a space. Over time, there is this name, rather than the space of the superficial literal domain name

Domain Name (English: Domain Name), also known as domain, is the name of a computer or computer group on the Internet composed of a string of names separated by dots, which is used to locate the computer during data transmission (sometimes also refers to geographic location). Because IP addresses are inconvenient to remember and cannot display the name and nature of the address organization, people have designed domain names, and used the Domain Name System (DNS, Domain Name System) to map domain names and IP addresses to each other, making people more Easily access the Internet without having to remember IP address strings that can be directly read by machines.

Space: Commonly known as "web space" is the meaning of the professional term "virtual host". It is to divide a server running on the Internet into multiple "virtual" servers. Each virtual host has an independent domain name and a complete Internet server (supporting WWW, FTP, E-mail, etc.) functions. Different virtual hosts on a server are independent and managed by users themselves. But a server host can only support a certain number of virtual hosts, when the number is exceeded, users will experience a sharp drop in performance. Virtual host technology is a technology used by Internet servers to save server hardware costs. Virtual host technology is mainly used in HTTP services. It logically divides a certain or all service content of a server into multiple service units, which are externally represented as multiple servers. Thereby making full use of server hardware resources. If the division is at the system level, it is called a virtual server.
