About RSS

RSS are files containing short descriptions of the content of a website in XML format. They make it possible to see the information on a site at a glance, and are designed for easy automated processing by programs.

They are often used to present an overview of the articles found on a site based on frequently-updated categories such as "News," "Press Releases," "What's New," "Blog," "IR News," and "Podcasts".

Using RSS eliminates the need to repeatedly check a website for updates, because you can see whether or not new information you are interested in has been posted before visiting.

www.iij.ad.jp delivers updates such as "Press Releases," "Announcements," and "News/Events" via RSS.
