Summary

NVIDIA Networking

Israel · AI-generated

business semiconductor datacenter israel

VOLTAIRE is the AS handle for NVIDIA Networking, formerly Mellanox Technologies.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to mellanox.com and netnames like NVIDIA and Mellanox.
  • With 1024 IPv4 addresses announced across 4 prefixes and only 3 observed neighbours, the inventory functions as a finely subdivided internal corporate estate rather than a transit or access network.

Notable

  • Registrants include Internet Binat Ltd for the 94.188.x.x blocks and BEZEQINT HOSTMASTERS TEAM for the 193.47.165.0/24 block, reflecting historical leasing or acquisition paths.
  • Mellanox acquired Voltaire in 2010, and NVIDIA subsequently absorbed Mellanox, rebranding the division as NVIDIA Networking.
  • The inventory consists of four /24 blocks, all located in Israel, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 440 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.
