AS23408 TBI-001
Unclassified ARIN
Summary
TBI-001
business leased mixed
The AS handle TBI-001 is held by an entity with a mixed address inventory comprising Comcast and Portland Trail Blazers space.
What it's used for
- The address space carries netnames
CCCH3-4(Comcast Cable Communications, LLC) andRIO-BLAZERS-66-178-131-0-24(Portland Trail Blazers). - The reverse DNS sample shows
cas1.ripcity.com, indicating the space supports corporate infrastructure for the Portland Trail Blazers. - With 512 IPv4 addresses announced across 2 prefixes and only 2 observed neighbours, the low neighbour count suggests a limited peering footprint or a specific access role rather than broad transit.
Notable
- Registrants do not agree with a single announcer identity; the space includes both Comcast Cable Communications, LLC and Portland Trail Blazers.
- The address inventory is small and fragmented, consisting of two distinct /24 blocks from different original owners.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,772 prefixes, as published 2026-10-15. 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.
