Summary
Cumberland Technologies International (PA.net)
isp legacy
CUMBERLAND-TECH is Cumberland Technologies International, the south-central Pennsylvania internet provider that trades as PA.net — the domain that stamps nearly all of this AS's reverse DNS.
What it's used for
RIS shows 23 announced IPv4 prefixes and 5,888 addresses, no IPv6, and 3 observed neighbours. Almost the whole footprint is a run of contiguous /24s out of 66.59.96.0–66.59.123.0, registered to Cumberland Technologies International itself under CTI-NET-1. A few thousand addresses behind three upstreams is an access provider, not a carrier.
What the space carries is written into the rDNS. Hosts resolve as wireless-66-59-115-133.rtr0.lg.pa.net, wireless-66-59-117-5.fsck.pa.net, 5ghz.qub4rt.circleeight.net, 66-59-118-133.mnrv.pa.net. The wireless- and 5ghz prefixes plus per-tower router labels are the signature of a fixed-wireless ISP: subscriber radios hung off named tower sites, each site getting its own rDNS sub-zone. Mixed in are static business assignments (ctifair2.static.rtr1.tc.pa.net) and customer-hosted services (mail.kasuru.com, an iDRAC management interface), which is normal for a rural WISP that also sells business circuits and colocation.
Notable
Two prefixes register elsewhere: 24.137.8.0/24 to PlanetCable Corp and 66.59.117.0/24 to an individual, Matthew Gillespie. Neither is a leasing signal — a customer or a partner operator's block announced by its upstream looks exactly like this, and the 66.59.117.x addresses still wear PA.net tower rDNS, so the space is plainly in Cumberland's own network. One sampled PTR reads 66-59-102-5.amazon.com. A PTR is published by whoever holds the reverse zone — Cumberland — and can name anything at all, so this is not evidence of Amazon infrastructure in the block; rDNS shows what space carries, never who holds it.

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 2026-10-18, 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 1,784 prefixes, as published 2026-10-19. 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.
