Summary

UPPERCUT services

Austria · AI-generated

business media vienna small

UPPERCUT-AS is held by UPPERCUT services (Ub services FlexCo).

What it's used for

  • The space carries corporate infrastructure for a media production company, as indicated by the netname UPPERCUT-NET and registrant 55 IT Services GmbH NOC.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and web services for a broadcast media production and distribution firm based in Vienna.

Notable

  • The registrant 55 IT Services GmbH NOC differs from the AS holder Ub services FlexCo, suggesting the IP space is managed by a specialized IT services provider or is a legacy allocation.
  • The address inventory is minimal, consisting of a single /24 block and a single /48 IPv6 prefix, typical for a small enterprise or creative agency.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
