What is the difference between the website with www and without?
A quick answer to this question is that there is no difference between two addresses for most modern domains. For example, writing www.wisegeek.com or wisegeek.com to a unified resource locator (URL) will bring you to this site with the same ease. However, the “www” from some websites can result in the browser to be unable to find a website. This problem is repaired by the domain holder. A brief understanding of how the World Wide Web (WWW) works will be useful in understanding the problem.
The Internet is a massive network of computers that communicate using agreed protocols. For example, every computer on the Internet is assigned a unique numerical address, so the information can be sent and received without being lost. These unique addresses are called Internet protocol addresses or IP. In the case of the site, the numeric IP maps the name because the names are easier for surfers to remember than numbers.
database databaseDomain names (DNS) contains a record for each web page that stores the site name and IP address. When clicking on the link or entering address in the web browser, the request will send the request to the DNS database to solve the name of the corresponding IP address. If the "WWW" prefix is omitted and a browser stops, it is likely that the DNS record does not contain a short version of the domain name: version without "www".
As soon as the name is found in the DNS database, it is resolved on the corresponding IP. This allows the browser to create a connection to the server that is the host of the site. It requires a page and adds your IP address, similar to the sending of self -service envelopes. The host server sends the web page to the computer and the transaction is completed.
In the past, many host servers have created websites like subdomains under www. , after the conventions of the name at that time. “Www” identified the server asWeb server, versus server dedicated to other tasks. Once the Internet has traveled widely through the general public, the ubiquitous "WWW" was often overlooked when entering the address of the website into browsers. This resulted in the lost operation of the website and a frustrated surfer, because many DNS records contained only www.example.com and not examples.com for the domain name.
Hosts over time began to attract the "WWW" designation for web servers and domains were created as examples.com . To capture traffic that could freely include "WWW" into the browser request, DNS records instead included another item that would cover this occurrence. Cname is a DNS brand that maps the main name alias in DNS: In this case "www". Name version. With this solution, surfers could include or exclude www. And add to the web in both directions.
DNS records can be edited to include a mapped alias. IfD You need this service for your domain, contact the domain registrar.
