Summary
Tennessee Valley Authority
TVA is the network of the Tennessee Valley Authority, the federally owned corporation created in 1933 that generates and transmits electricity across Tennessee and parts of six neighbouring states, and manages the Tennessee River system.
What it's used for
RIS sees 15 IPv4 prefixes carrying 131,072 addresses and one IPv6 /32 (2604:700::/32). The v4 space is two legacy Class-B blocks, 152.85.0.0/16 and 152.87.0.0/16, announced both whole and deaggregated into halves and individual /24s. Two full /16s for a single organisation is a 1990s-era allocation, and the deaggregation pattern (a /16, its two /17s, then selected /24s) is what a large enterprise does to steer traffic between sites or transit links rather than anything a service provider would do.
This carries a power utility's corporate and operational IT: offices, generating plants, substations, dam and river-management sites, and the business systems behind them.
Notable
The kind is government, and the evidence rather than the name settles it. TVA is a US federal agency, wholly owned by the government, and its 131,072 addresses are matched by only three observed BGP neighbours — an enterprise with a couple of transit providers, not a network that sells anything. No eyeball ISP or carrier peers with three ASes.
Interesting
The IPv4 holding is far larger than the network's actual host count needs. It is an artefact of pre-CIDR allocation policy: apply early, get a /16, keep it forever.

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.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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.
