Summary
Bitwise Internet Technologies, Inc.
hosting legacy
BITWISE is Bitwise Internet Technologies, Inc., a small Boston, Massachusetts
internet and hosting company.
What it's used for
- Internet connectivity, web and server hosting, and network services for business customers in the Boston area.
- The announced space is a handful of legacy blocks, used for hosted systems and customer assignments rather than a large subscriber base.
Notable
- Bitwise is a long-lived independent operator rather than a carrier, and the registry contacts have been stable for a very long time, which is unusual in a space where small ISPs are typically absorbed or shut down.
- The ARIN autnum registration dates to 1994, and the announced prefixes are legacy
204.xand207.xblocks from the same era.
Interesting
- Boston's early concentration of universities and technology companies produced a wave of small commercial ISPs in the mid-1990s. Very few of the ASNs handed out then are still announced by their original holder.
