...as it has become common to refer to us as "the ARPA2 project". In reality however, you can find us at:
InternetWide.org is our public-facing blog and news channel.
The project's overall name is InternetWide, and the outline of our work is the InternetWide Architecture.
Concrete projects are usually called "ARPA2 xxx" and may have a subdomain http://xxx.arpa2.net but there is no guarantee — you should follow those links from other places to be sure.
We use this domain for infrastructure, such as demos and test data, as well our own contact addresses. We also post a number of registries here, such as for our OID range and commonly used UUID identifiers.
