Summary

State Universities Retirement System

United States of America · AI-generated

government business illinois retirement

The AS handle SURS is held by State Universities Retirement System.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by registrant netnames ICN9 and ICN4 assigned to Illinois Century Network.
  • The inventory consists of 512 IPv4 addresses across 2 prefixes, with a single observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.

Notable

  • The RDAP registrants for both announced prefixes are Illinois Century Network, which differs from the AS holder name but aligns with the Illinois state government context.
  • The State Universities Retirement System is an Illinois state agency that administers retirement, disability, death, and survivor benefits to eligible participants.
  • The address inventory is minimal, comprising two /24 blocks: 64.150.70.0/24 and 209.175.175.0/24.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
