RSS Feeds at ARIN

What is RSS?

RSS has many different definitions but is commonly understood to be an acronym for "Really Simple Syndication." It is an umbrella term for a suite of formats used to publish frequently updated content online. The syndication is done through a file that uses XML markup to include titles, summaries, links, and descriptions of content.

Why is ARIN publishing RSS feeds?

ARIN publishes these feeds to make it easier for the community to follow announcements and discussions, share this information with colleagues, and increase the level of involvement with ARIN. While subscribing to ARIN mailing lists, such as ARIN-Announce or the Public Policy Mailing List, is still the best way to stay informed and involved, ARIN's RSS feeds offer many benefits, including the ability the flexibility of providing structured content to a variety of applications, such as a personal or web-based feed aggregator or custom scripts.
