Summary

Viacom Informatics

Hungary · AI-generated

business hungary corporate

The AS handle VIACOMKFT is held by Viacom Informatics Ltd.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames HU-VIACOM-20091208 and VIACOM and reverse DNS entries such as web-3-128.e-tiger.net and pegazusgumi.hu.
  • The network announces 1536 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and web services for the company and its associated entities.

Notable

  • All registrants for the announced prefixes are listed as Viacom Informatics Ltd., matching the AS holder.
  • The address inventory is compact, consisting of two /23 blocks and two /24 blocks in IPv4, plus a single /32 in IPv6.

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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
