Summary
Office of the Comptroller of the Currency
government legacy
OCCAS belongs to the Comptroller of the Currency — the OCC, the bureau of the U.S. Treasury that charters, regulates and supervises national banks and federal savings associations. This is a federal regulator's own network, not a service provider of any kind.
What it's used for
The routing is tightly contained and entirely self-consistent. RIS sees seven IPv4 prefixes and 1,792 addresses, all of them inside the 199.83.32.0 neighbourhood — 199.83.34.0/24 through 199.83.40.0/24 plus the covering 199.83.40.0/23. There are three observed neighbours and no IPv6. A few transit links and a couple of thousand addresses is a federal agency publishing its public-facing systems and remote-access edges: the bank-examination workload behind them lives on private space, and the AS exists so the agency can multihome without renumbering.
Every single prefix is registered in ARIN to the Comptroller of the Currency under the NETBLK-OCCNET handle. Holder, registrant and originator are one organisation across the whole inventory, with no third-party registrants at all — the cleanest possible clearance against the IP-leasing pattern, and the reason this can be called government with confidence.
Notable
No PTRs came back on the fourteen addresses sampled. That is a sample, not a finding, and nothing is inferred from it here; a regulator's public estate having sparse reverse DNS is unremarkable either way. The classification rests on the ARIN org and the contiguous self-registered block, both of which are positive evidence.

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 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
