Yes, if your http server is not set up to do the logical<br />
name lookup for you, then you will receive the IP address.<br />
Or if it cannot give you the logical name, then it could<br />
also give you the IP address. &nbsp;I like to just use the<br />
REMOTE_ADDR and do the lookup myself in my code when needed,<br />
since it makes the http server faster if it doesn't have<br />
do the lookup on the logical address for every page served.<br />

When I try to get $ENV{'REMOTE_HOST'} in my Perl-script it only returns the IP-address. Why? I use Internet Information Server. Is it some kind of setting needed to enable the DNS lookup?

$ENV{'REMOTE_HOST'} is not availible in IIS.

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.
