About Webspace

About Webspace

About Webspace – A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web.

Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center.

Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.

The scope of web hosting services varies greatly.

The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface.

The files are usually delivered to the Web “as is” or with minimal processing.

Many Internet service providers (ISPs) offer this service free to subscribers.

Individuals and organizations may also obtain Web page hosting from alternative service providers.

Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense.

Single page hosting is generally sufficient for personal web pages.

A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP, Java, Ruby on Rails, ColdFusion, or ASP.NET).

These facilities allow customers to write or install scripts for applications like forums and content management.

Also, Secure Sockets Layer (SSL) is typically used for e-commerce.

The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail.

Some hosts specialize in certain software or services (e.g. e-commerce), which are commonly used by larger companies that outsource network infrastructure.

Whois – This is a PHP application to let you find the owner and technical responsible of any web IDNA domain name as defined in RFC3490, RFC3491, RFC3492 and RFC3454.

It also supports IP/AS whois queries which are very useful to trace SPAM. You just only need to pass the dotted quad IP address or the AS, Autonomous System (Internet) handle instead of the domain name. Limited, non-recursive support for Referral Whois (RFC 1714/2167) is also provided.


Here below you will find a form field which you should use as follows:

  1. write in the form field the domain name you want to find information about:
    • you may use a hostname, like google.com. Do not use http://, ftp:// or any other URL scheme name (WWW protocol). Some domains require the use of prefix “www.”, other not.
    • you may use an IP address (IPv4 format), like
    • or you may use an AS number, like AS45566
  2. Click the button «search»
  3. Wait a couple of seconds for query to be processed and then you will be able to read all available information for the domain you wish to run a query about.
