Summary

Ypsilon.Net AG

Germany · AI-generated

business travel payments it

YPSILON-AS is held by Ypsilon.Net AG.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netnames DE-YPSILON-20150220 and YPSILON-NET2 and the reverse DNS record f1-fcmportal.infosys.de.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of web and API endpoints for Ypsilon.Net's integrated IT, payment processing, and fraud prevention services, supporting its role as a travel industry technology provider.

Notable

  • Registrants for both prefixes are Ypsilon.Net AG and Ypsilon.Net Guardian, aligning directly with the AS holder.
  • Ypsilon.Net AG is a German company established in 1997, providing IT and payment solutions specifically for the travel sector, with certifications including PCI DSS Level 1 and ISO 27001.
  • The inventory consists of two contiguous IPv4 prefixes in Germany, with no IPv6 prefixes announced.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
