What Is Domain Resolution and How It Works
Domain Resolution Definition
Domain Resolution is a service that points the domain name to the website infinite IP so that people can easily access the website through the registered domain proper name. An IP address is a numeric address that identifies a site on the network. In club to facilitate the retentivity, the domain name is used instead of the IP address to place the site address. Domain resolution is the process of converting domain names to IP addresses. The resolution of the domain name is washed by the DNS server.
Domain resolution is likewise called domain pointing, server settings, domain configuration, contrary IP registration, and then on. To put it but, the easy-to-call back domain proper name is resolved into IP. The service is completed by the DNS server, which resolves the domain name to an IP accost, and then binds a subdirectory to the domain name on the host of this IP accost.
The address on the Internet is a digital IP address, and the main purpose of domain resolution is to facilitate memory.
How Domain Resolution Works
After registering a domain name with a domain registrar, how can I encounter the content of my website? In a professional person term, information technology is called "domain name resolution".
The domain name is a fix of address conversion systems especially established for the convenience of memory. To admission a server on the Cyberspace, it must ultimately exist achieved through an IP accost. Domain proper noun resolution is the process of converting a domain proper noun into an IP address. Ane domain proper noun corresponds to one IP address, and one IP accost can correspond to multiple domain names; therefore, multiple domain names tin can be resolved to one IP address at the same time. Domain proper name resolution needs to be completed by a defended domain name resolution server (DNS).
Domain Resolution Process
For instance, if a domain proper name is abc.com, if y'all want to visit the website, it must exist resolved. First, resolve to a fixed IP of a Web server: 211.214.1.XXX through a dedicated DNS server from the domain registrar. Then, the domain proper name is received through the WEB server, and the domain name abc.com is mapped to this server. Finally, enter the domain proper name abc.com to admission the website content. This realizes the whole process of domain name resolution.
People are used to remembering domain names, merely machines only recognize each other's IP addresses. In that location is a correspondence betwixt domain names and IP addresses, and the conversion between them is called domain proper noun resolution. Domain proper name resolution needs to be completed by a dedicated domain resolution server, and the whole procedure is automatic.
Computers on the Internet are located by IP addresses. Given an IP address, you can find a certain host on the Net. And because IP addresses are difficult to remember, domain names were invented to supercede IP addresses. However, the host to exist accessed cannot be institute directly through the domain name. A process of looking upward the IP accost from the domain name is added in the middle. This procedure is domain name resolution. After the domain name is registered, the registrar provides free static resolution services for the domain name. General domain name registrars do not provide dynamic resolution services. If you demand to use dynamic resolution service, you need to pay for it.
