Summary

TSYS

United Kingdom · AI-generated

business financial payment corporate

The AS handle TSYS-AS is held by Total System Services Processing Europe Limited.

What it's used for

  • The space carries corporate infrastructure for payment processing, evidenced by the reverse DNS record bcsuaapi.tsyseurope.com and the netname TSYS-EUROPE.
  • The inventory consists of a single IPv4 prefix, 194.150.182.0/23, comprising 512 addresses, with 0 IPv6 prefixes announced.
  • With only 1 observed neighbour in the routing system, the low address-to-neighbour ratio indicates this is an internal corporate estate rather than a transit or access network.

Notable

  • The registrant Total System Services Processing Europe Limited matches the AS holder, confirming direct ownership of the address space.
  • TSYS is an American financial technology company that provides payment processing and merchant services; this AS represents its European operational entity.
  • The address inventory is a single contiguous /23 block, typical of a dedicated corporate allocation for specific business units or data centers.

Reputation

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 1,784 prefixes, as published 2026-10-19. 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.
