AS11121 FIRSTDATACORP-DB

FIRSTDATACORP-DB is held by Fiserv Solutions, LLC, the payments and financial-technology company headquartered at 255 Fiserv Drive, Brookfield, Wisconsin. The handle still carries the name of First Data Corporation, the card-processing giant Fiserv merged with in 2019 — the AS was never renamed after the deal.

What it's used for

A small, tightly-scoped corporate network. RIS observes 2 IPv4 prefixes totalling 512 addresses — the adjacent 198.62.137.0/24 and 198.62.138.0/24 — and no IPv6. With one observed BGP neighbour, nothing about this AS suggests a provider role. It is a pair of /24s announced by one company for one purpose.

Both prefixes are registered to MICR-1STPOS, an ARIN network object whose organisation is Fiserv Solutions, LLC. The registrant and the announcing holder are therefore the same company, despite the mismatched names — the network name is simply an artifact of an older internal designation that ARIN never had reason to change.

Notable

The 1STPOS in that network name is the most informative string in the whole record: point-of-sale. Card-present payment processing is First Data's historic core business, and a couple of /24s single-homed behind one upstream is what a payment-network endpoint looks like — a small, static, tightly-controlled range that merchant terminals and acquiring systems talk to, not a general-purpose corporate estate.

Fiserv is a very large company; this AS is not a very large network. That is normal. Enterprises of this size run most of their footprint inside carrier and cloud space, and keep a legacy ASN like this one alive for the specific systems that need a fixed, independently-routed address.
