Unclassified ARIN
Summary
Xilinx
semiconductor business corporate fpga
XILINX is the autonomous system for Xilinx Incorporated, a semiconductor company specializing in field-programmable gate arrays.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by reverse DNS entries such as
unknown-191-255.xilinx.comandunknown-223-254.xilinx.com. - The AS announces 65536 IPv4 addresses across 20 prefixes with 12 observed neighbours, a ratio consistent with a large internal corporate estate rather than a transit or access provider.
Notable
- All registrants in the RDAP sample are listed as
Xilinx Incorporated; Hostmasterwith the netnameXILINX, fully agreeing with the AS handle. - Xilinx was acquired by Advanced Micro Devices (AMD), which now operates the company as a subsidiary.
- The inventory consists of a single contiguous block (149.199.0.0/17) subdivided into 20 smaller prefixes, indicating site-by-site segmentation of the corporate network.

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
11 upstream, 0 downstream and 11 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 2026-11-03, 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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
