Summary
CU*Answers
business financial legacy corporate
The AS handle WESCO is held by **CUAnswers, Inc.*
What it's used for
- The address space carries corporate infrastructure for a financial services provider, evidenced by reverse DNS entries pointing to
cuanswers.comandcubase.org. - The inventory consists of 3,584 IPv4 addresses across 8 prefixes, with 6 observed routing neighbours, indicating a small internal corporate estate rather than a transit or access network.
Notable
- Registrants are split between **CUAnswers, Inc. and CenturyLink Communications, LLC*, with the latter holding legacy Qwest netnames such as
CENTURYLINK-LEGACY-QWEST-INET-9. - The address inventory is a mix of legacy Qwest blocks and CU*Answers-specific allocations, reflecting the historical acquisition of Qwest's network assets by CenturyLink and subsequent corporate rebranding.
- One prefix,
66.115.246.0/24, shows reverse DNS pointing tosdnet.net, suggesting a specific regional or legacy segment within the broader corporate footprint.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
6 upstream, 0 downstream and 6 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
