AS11273 — FDCSGNET
AS11273 announces 88 IPv4 prefixes covering 160,000 addresses and 0 IPv6 prefixes.
About this network
FDCSGNET belongs to Fiserv Solutions, LLC — the handle is FDC, First Data Corporation, the payments processor Fiserv acquired in 2019. This is a corporate network of one of the largest merchant-acquiring and card-processing businesses in the world, not a service-provider network.
What it's used for
RIS observes 143 IPv4 prefixes carrying roughly 161,000 addresses, no IPv6, and only three observed neighbours. That combination is the whole story. A network announcing 143 prefixes with three BGP adjacencies is not selling transit to anyone: it is a very large enterprise multihomed across a couple of carriers. Compare a wholesale carrier of the same address size, which would show neighbours in the hundreds.
The heavy deaggregation is what a payments estate looks like after thirty years of acquisitions. The inventory is anchored by two legacy /16s, 167.16.0.0/16 (FDCNET) and 170.186.0.0/16 (FDCNET-2), then a long tail of /21s, /22s and /23s from unrelated blocks — 216.66.216.0/21, 208.72.248.0/21, 50.58.8.0/22, 192.131.68.0/22, 166.73.x, 12.184.102.0/23 — each of which arrived with a processor or platform that First Data bought. The space carries merchant and partner connectivity: terminal and gateway endpoints, extranet links to card networks and banks, settlement and authorisation infrastructure, and the company's own data centres.
Notable
Every prefix RDAP resolved is registered to Fiserv Solutions, LLC, under handles like FDCNET, IPS-WEB and CHAN-TELECH. Different-looking network names, one org, and no third-party registrant anywhere — a clean first-party inventory despite how scattered the address blocks are. Scatter alone is never the leasing signal; unrelated registrants are.
Interesting
The reverse DNS has not caught up with the merger. 216.66.216.5 and 208.72.248.5 still answer as ns10.firstdatacorp.com and ns11.firstdatacorp.com, and 216.66.218.5 as cat.umb360.firstdata.com. Years after the acquisition, the nameservers of a company that no longer exists still front a payments network that now belongs to Fiserv.
