Domains, Servers, and Static IP Addresses
Wednesday, December 26th, 2007
When you buy a domain name, the registrar assigns a primary and secondary IP address to the name. An Internet Protocol (IP) address is a set of numbers like this: 12.345.678.90. Each computer connected to the internet has an IP address. Some have permanent IP addresses. A server has a permanent (static) IP address which identifies where your website will physically live.
When you logon to the net at home, your computer has an IP address. Some computer get a different number (IP Address) each time you logon. But web servers have permanent IP addresses and and so do domain names, and when you buy a domain, you need to tell the registrar the IP address or the domain name of the computer on which the site is. This info is sent to hubs and routers around the world that are called Domain Name Servers (DNS). When people enter your url into their browser, they will find your home page. DNS servers are like giant telephone directories that look up your domain name and find the IP address of the computer, and routes the browser’s call for a page to the right place.
