Apache Newbe question

[quaked2023]

Hello!

This is my first time installing apache http server, and i have a question.... I downloaded the apache_2.0.52-win32-x86-no_ssl.msi file from apache.org, but now that i want to install it i, it tells enter my server information, Network Domain, Server Name, and Administrator's Email Address, by default i don't know why it already has things there like in Network Domain it has telnor.net, on Server Name it has red-corpb8-6-208.telnor.net and on Administrator's Email Address it has admin@telnor.net, now telnor is my ISP but my email address is not admin@telnor.net, i found this page that explains how to install apache with windows

http://httpd.apache.org/docs-2.0/platform/windows.html

but my question is what DNS should i put, the one that's already there or what, i don't understand what server they mean can you help me?

Thanks in advance!
