Summary
Osir, Inc.
legacy
ZT-75-11867 is held by Osir, Inc., with an ARIN address at 131 Continental Drive, Suite 305, Newark, Delaware. The AS number is a recent reissue, not an old network: ARIN's record for it was created in February 2025. What the network is actually for could not be established, so this card describes rather than classifies.
What it's used for
Not determined. RIS observes no IPv4 prefixes at all and three IPv6 prefixes: 2602:f700::/48, 2602:f700:2::/47 and 2602:f700:53::/48, against two observed BGP neighbours. An IPv6-only AS with a couple of upstreams is unusual but perfectly legitimate; it is simply too little routing surface to infer a workload from.
The addressing is self-registered. ARIN records 2602:f700::/48 under the netname ZANA-TECH-PRIMARY to Osir, Inc. at the same Newark address, created in February 2025. So the announcer and the registrant are the same party, and the space is not being flown for a third party. Two names for one operator (the handle's ZT, the netname's ZANA-TECH) is naming, not a red flag.
Notable
The evidence stops there. A web search turned up no public presence under either name, no reverse DNS was captured for the announced IPv6, and there is no IPv4 to sample. A Delaware suite address plus a 2025 registration is consistent with a small or newly formed operator, and equally consistent with several other things.
With no observable use, the honest answer is other at low confidence. Guessing hosting from an empty routing table would be inventing a finding.

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 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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 1,784 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.
