About this network

The network of OWC, the Illinois company that sells memory, storage and upgrades for Apple hardware.

What it's used for

• Corporate and storefront systems. 1,792 addresses over five prefixes with one observed BGP neighbour.

Notable

• All five blocks sit inside 69.64.132.0–69.64.143.255 and share one netname, OWC-NET-BLOCK-A — a single allocation announced as two /23s and three /24s.
• The one sampled reverse name is 128.140.64.69.arpa.owc.net: the address reversed octet-by-octet, the arpa label kept, and the company's own domain pasted on where in-addr.arpa should be.
• First seen in the routing data in October 2004, later than most of its numeric neighbours.

Interesting

• That reverse name is a template filled in one step too far. Reverse DNS lives under in-addr.arpa, so the generator that built 128.140.64.69.in-addr.arpa was reused to build a forward name and carried the arpa label along with it. It resolves, it is unambiguous, and it has evidently never bothered anyone enough to fix.
• A retailer selling upgrades for one manufacturer's computers is a narrow business to build a company on, and OWC has been at it since the Mac was beige. The address footprint matches: one allocation, one netname, one upstream, no growth into anything it did not need.
