Summary

Fiserv Solutions (First Data)

United States · AI-generated

enterprise legacy

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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
