Summary
Bank of America, N.A.
enterprise legacy
BANKAMERICA is one of the autonomous systems of Bank of America, National Association, the retail and commercial banking arm of one of the largest US bank holding companies. RIS sees 266 IPv4 prefixes carrying 110,592 addresses, no IPv6, and 19 observed neighbours.
What it's used for
The bank's own global network edge. The bulk of the space is a contiguous run through 171.158.0.0–171.161.255.255 plus 171.192.0.0/20, announced as a mix of /19s, /20s and /21s with heavy deaggregation down to smaller blocks, alongside ARIN 199.43.64.0/21 and 199.43.72.0/21. This is internet-facing bank infrastructure: online and mobile banking, ATM and branch connectivity, partner and clearing links, mail and remote access. None of it is resold, and none of it is hosting.
Notable
The numbers tell the story better than any description. 110,000 addresses is a large network by any measure, comparable to a mid-size ISP, but only 19 observed neighbours. A carrier with that much space would peer with hundreds or thousands of ASes. A handful of neighbours against a very large address count is the fingerprint of a big enterprise: a lot of internal estate, a small number of upstreams, and no transit customers. It is one of the clearest examples of why address count alone cannot classify a network.
Interesting
266 announcements for what is fundamentally a few large aggregates means the routing is fragmented far beyond what reachability requires. That is common in banks: prefixes get split for traffic engineering, per-site multihoming and DDoS-scrubbing handoffs, and once split they rarely get re-aggregated. There is no IPv6 in the announcement set at all.

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.
Transit providers
18 upstream, 1 downstream and 19 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 2026-10-14, 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 1,772 prefixes, as published 2026-10-15. 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.
