Summary
Altopia Corporation
hosting legacy
Altopia Corporation of Seattle, Washington — a long-running commercial Usenet
(NNTP news) service provider, operating since the mid-1990s.
What it's used for
- Serving Usenet news to paying subscribers. The AS announces a single /22 and an IPv6 /48; reverse DNS on the space resolves under
alt.net, Altopia's own domain. - The address space is service infrastructure — news servers — rather than customer access networks. Altopia's customers connect to this network from wherever their own ISP puts them.
Notable
- Altopia is one of the oldest independent Usenet providers still trading, and is known for running an uncensored, unfiltered news feed.
- The ARIN record dates to 1997, so unlike some of its neighbours in the 6400s the low AS number here does reflect an early registration.
Interesting
- Usenet providers are an unusual shape on the modern internet: a small address footprint carrying a very large amount of outbound traffic. Altopia's tiny prefix count next to its multi-peer presence is a good illustration.
