Unclassified ARIN
Summary
Vornado Realty Trust
business real-estate corporate
VORNADO-PUBLIC is the public-facing autonomous system for Vornado Realty Trust.
What it's used for
- The address space carries corporate infrastructure for a major real estate investment trust, with one prefix registered directly to the company (
UU-63-118-131-D4) and another registered to Cogent Communications (COGENT-A). - The AS announces 512 IPv4 addresses across 2 prefixes and maintains 4 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.
Notable
- Registrants do not fully align with the announcer; the 38.105.239.0/24 block is registered to Cogent Communications, LLC, while the 63.118.131.0/24 block is registered to Vornado Realty Trust.
- The address inventory is minimal, consisting of two /24 blocks, which reflects the limited public IP footprint typical of a large private enterprise network.

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 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
