Summary

4iG Telecommunications Holding Zrt

Hungary · AI-generated

telecom business hungary

AHRT-PRO-AS is operated by 4iG Telecommunications Holding Zrt.

What it's used for

  • The address space carries corporate and legacy infrastructure, evidenced by netnames HU-IRISZ-20060919 and Antenna-Hungaria-130-93-192-0.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained corporate estate rather than a transit or large access network.

Notable

  • Registrants for both announced IPv4 prefixes are listed as 4iG Telecommunications Holding Zrt, aligning with the AS holder.
  • The operator formerly operated under the name Antenna Hungaria, as reflected in the netname Antenna-Hungaria-130-93-192-0 and PeeringDB records.
  • The inventory consists of two /24 IPv4 blocks and a single /48 IPv6 block, representing a modest internal corporate address space.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
