Summary
B3zdna Systems Inc.
B3ZDNA is B3zdna Systems Inc., a Canadian company that markets itself as a "high security networking" and quantum-communication outfit. AS10261 is a small stub network — a single /24 and a single /48 behind one upstream.
What it's used for
Not determinable from the evidence, and this card says so rather than guessing. The AS announces one IPv4 prefix, 148.227.175.0/24 (256 addresses), and one IPv6 prefix, 2620:ba:6000::/48, with exactly one observed BGP neighbour. One neighbour and one /24 is a textbook stub: the network buys transit, announces its own space for provider independence, and carries no traffic for anyone else. Its upstream is a Toronto-based carrier, which is consistent with the .ca identity.
Nothing further can be read from routing. The company's public web presence is a single page with an email address on it — enough to confirm the holder exists and is Canadian, not enough to establish what the addresses actually serve.
Notable
Classified other, low confidence — an honest answer, not a failure. The operator is identifiable; the use is not. Do not read the marketing language as a network fact: "quantum communication" is what the company says it sells, and says nothing about what a packet from this /24 is doing.
Interesting
The surrounding 148.227.0.0/16 is legacy space whose other /24s route to unrelated Mexican networks, including university address space. Geolocating this /24 by its neighbours in the numbering plan would put it in the wrong country — the ASN and the ROA are the only reliable guides here.

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 1,773 prefixes, as published 2026-10-13. 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.
