Summary

AS54891 is held by Cathron Information Consulting.
What it's used for
- The address space carries two IPv6 prefixes:
2602:81d::/47and2602:81d:2::/48. - With zero IPv4 prefixes announced and three observed neighbours, the inventory suggests a small-scale enterprise or consulting network rather than a large access or transit provider.
- Traffic from this AS consists of enterprise networking services and resilient infrastructure solutions provided by the consulting firm.
Notable
- The registry holder is CATHRON INFORMATION CONSULTING, matching the AS handle
CATHRON-INFO-MAIN. - The address inventory is limited to two IPv6 prefixes with no IPv4 allocation, indicating a modern, IPv6-centric deployment for a small professional services firm.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
