About this network

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 is ASCENSUS, one is Ascensus College Savings under ACS-PUBLIC-1, one is Upromise Investments under CERF-UPROMISE-A, and one is Comcast under CCCH3-4.
• 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-A is 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.
