Summary
Advanced Corporate Network
isp business legacy
Advanced Corporate Network is a US provider selling connectivity to business customers.
What it's used for
- Business internet access from a single block held in its own name.
Notable
- One prefix, announced whole:
216.47.160.0/19, registered asACN-BLK-01. 8,192 addresses, four observed BGP neighbours. - Holding the space directly rather than taking it from an upstream is what makes those four neighbours useful — provider-assigned addresses can only be announced through the provider that assigned them.
Interesting
- A single un-deaggregated
/19is a rare thing in the modern routing table. Most networks this size have accumulated extra blocks over the years, or split what they have to steer traffic. One prefix, one netname, four upstreams is a network that got what it needed at the start and never had to go back.

Peering at a glance
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 2026-10-20, 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 1,778 prefixes, as published 2026-10-20. 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.
