ARPA.NET provides DNS and e-mail services for its friends.

This is not the original ARPANET, which was decommissioned in 1990 after the original organization evolved into the Defense Advanced Research Projects Agency. We remember it fondly, however, and have styled the ARPA.NET domain in the spirit of the old ARPANET.

On two occasions ARPA.NET servers have reached 1000 days of continuous uptime, NS0.ARPA.NET on 20 May 2001 and LL.ARPA.NET on 18 October 2020.
