business software us

NEXUSTEK-LASASN01 is held by Nexus Technologies, LLC.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames such as CYBER-NEXUSTEK-LV01, CYBER-ZUMASYS-01, and NEXUSTEK-LASNET01 through NEXUSTEK-LASNET03.
  • The AS announces 3584 IPv4 addresses across 5 prefixes with 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal office workers and software development endpoints, as Nexus Technologies provides custom software solutions and maintenance services.

Notable

  • Registrants are consistent with the announcer, with most prefixes registered to Nexus Technologies, LLC and one prefix (162.42.16.0/22) registered to NexusTek Irvine, LLC.
  • The address inventory is finely subdivided into five distinct /22 and /23 blocks, reflecting site-by-site segmentation for a corporate entity.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
