Summary

Columbia Energy L.L.C

United States of America · AI-generated

business energy corporate

The AS handle COLUMBIA-ENERGY-LLC is held by Columbia Energy L.L.C.

What it's used for

  • The address space carries corporate infrastructure for an energy company, evidenced by registrant names like Columbia Energy L.L.C and netnames such as CEL-54 and NOANET-BLK2-CEL54-2.
  • The network announces 5120 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating an internal corporate estate rather than a transit or access provider.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to Columbia Energy L.L.C, though one prefix (64.146.230.0/24) is registered to Northwest Open Access Network; DNS and IP Role Account.
  • The address inventory is finely subdivided into multiple smaller blocks, consistent with site-by-site segmentation for a large corporate entity.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
