Summary

Progress Software

United States of America · AI-generated

business software corporate

PSC is the autonomous system for Progress Software.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname PSCNET registered to Progress Software.
  • The AS announces 1024 IPv4 addresses across 2 prefixes with 3 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.

Notable

  • Registrants do not fully agree with the announcer; one prefix is registered to Zayo Bandwidth with netname ZAYO-CCF-131-239-0-0, while the other is registered to Progress Software.
  • The address inventory is small and finely subdivided into two /23 blocks, indicating site-by-site segmentation for a single corporation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
