enterprise business legacy

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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,852 prefixes, as published 2026-11-08. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
