Summary

Retirement Systems of Alabama

United States of America · AI-generated

government business internal

RSA-AL is the autonomous system for Retirement Systems of Alabama.

What it's used for

  • The address space is registered under the netname BELLSNET-BLK18 with registrant AT&T Enterprises, LLC, indicating the space is leased or historically associated with AT&T infrastructure.
  • The AS announces a single IPv4 prefix, 74.254.150.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour in RIS, the low neighbour count relative to the address block suggests an internal corporate or government estate rather than a transit or access provider.

Notable

  • The RDAP registrant AT&T Enterprises, LLC differs from the AS holder Retirement Systems of Alabama, reflecting the leasing or historical allocation of the address space from AT&T.
  • The inventory consists of a single contiguous /24 block, typical of a specific site or departmental allocation within a larger corporate or government network.

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.
