Summary

Siemens Industry Software

Ireland · AI-generated

business corporate eda software

SIEMENS-INDUSTRY-SOFTWARE-ARMENIA is held by Siemens Industry Software Limited.

What it's used for

  • The space carries corporate infrastructure for Siemens Digital Industries Software, evidenced by the netname SIEMENS-DISW-7 and registrant Siemens Industry Software Inc.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and engineering endpoints for Siemens' product design, simulation, and verification software divisions.

Notable

  • Registrants align with the announcer, listing Siemens Industry Software Inc. for the prefix and Siemens Industry Software Limited as the registry holder.
  • The operator is the successor to Mentor Graphics, which was acquired by Siemens in 2017 and subsequently renamed Siemens EDA before being integrated into Siemens Digital Industries Software.
  • The address inventory consists of a single /24 block located in Ireland, consistent with a centralized corporate presence.

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 1,773 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.
