United States of America · AI-generated

business analytics us

The AS handle PLUS-1 is held by Plus Analytics, LLC.

What it's used for

  • The address space carries the netname OPTIGFX-NET across all three announced prefixes, with registrants listed as ALPHAREL/optigraphics Corporation and LightEdge contacts.
  • The AS announces 768 IPv4 addresses across 3 prefixes and has 1 observed neighbour, indicating a small, isolated corporate or internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints for an advanced analytics and predictive modeling company based in Chicago.

Notable

  • The registrants for the announced prefixes (ALPHAREL/optigraphics Corporation, LightEdge) differ from the current AS holder (Plus Analytics, LLC), suggesting the address space was previously associated with different entities or leased.
  • The inventory consists of three /24 blocks within the 147.203.0.0/16 range, all located in the United States.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
