AS32764 CPN
Unclassified ARIN Educational/Research
Summary
Cisco Internet Routing Labs
research education cisco testbed
CPN is operated by Cisco Internet Routing Labs.
What it's used for
- The address space is registered to CSN Support Services with the netname
CPN, aligning with the registry holder. - The AS announces a single IPv4 prefix,
199.66.188.0/24, and one IPv6 prefix,2602:f98b:10::/48, for a total of 256 IPv4 addresses. - With only 1 observed neighbour, the low address-to-neighbour ratio indicates a specialized research or testbed environment rather than a commercial transit or access network.
Notable
- The registrant CSN Support Services matches the AS handle
CPN, confirming consistent ownership across registry records. - Secondary sources identify the operator as CIRL (Cisco Internet Routing Labs), an educational and research facility associated with Cisco.
- The inventory consists of a single /24 block, representing a compact and self-contained address estate typical of internal lab infrastructure.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 2 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 2026-10-28, 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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
