United States of America · AI-generated

business corporate retail apparel

The AS handle CSC-ASN is held by Columbia Sportswear Company.

What it's used for

  • The space carries corporate infrastructure, identified by the netname CSC-54067 and registrant Columbia Sportswear Company; Datacom.
  • The AS announces 512 IPv4 addresses within a single prefix (204.48.44.0/23) and maintains 4 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, web/API endpoints, and internal systems for a global outdoor apparel manufacturer based in Portland, Oregon.

Notable

  • The registrant Columbia Sportswear Company; Datacom aligns with the announcer, confirming the space is owned by the company.
  • The address inventory is compact, consisting of a single /23 block, which is typical for a corporate network segmenting its internal infrastructure.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
