Unclassified ARIN
Summary
Ascensus
finance enterprise legacy
The network of Ascensus, which administers retirement and college savings plans for US employers and state programmes.
What it's used for
- Plan administration and customer-facing services. 2,560 addresses over six prefixes, five observed BGP neighbours, no IPv6 announced.
Notable
- Six prefixes carry five different registrants. Two are Ascensus itself under
ASCEN-53, one isASCENSUS, one is Ascensus College Savings underACS-PUBLIC-1, one is Upromise Investments underCERF-UPROMISE-A, and one is Comcast underCCCH3-4. - The single sampled reverse name is
ugift529.demo.acs529.com— a demo host for the gifting feature of a 529 college savings plan.
Interesting
- This is an acquisition history announced in BGP. A company that grows by buying plan administrators inherits their address space, and address space is one of the few assets that keeps the old owner's name attached to it in public.
CERF-UPROMISE-Ais the deepest layer. CERFnet was the California Education and Research Federation Network, an early regional provider that ended up inside AT&T, and it assigned this block to Upromise long before Upromise's savings business became part of Ascensus. Two companies that no longer exist under those names are both still legible in one netname.- A Comcast-registered block announced by the customer rather than by Comcast is the ordinary arrangement for a business that wanted portable-looking space without qualifying for its own.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
