Summary
Antenna Hungária (4iG)
isp legacy
AHRT-AS is the network of Antenna Hungária, Hungary's broadcast-transmission and telecoms operator, now held by 4iG Telecommunications Holding Zrt after 4iG acquired the company in 2021.
What it's used for
- Internet access carried over Antenna Hungária's own infrastructure. Large parts of the announced space use generic per-address pool naming of the form
NNN-NNN-NNN-NNN.mpool.ahrt.hu, the signature of end-user access pools rather than servers. - Wholesale and downstream service: several of its prefixes are sub-assigned to small Hungarian regional ISPs, whose own subscriber naming shows up inside AS8990's space (
wave-net.hu,orosnet.hu,bodajknet.hu,ons.hu,szivarvanynet.hu). - Business connectivity: some blocks are PA assignments to named Hungarian companies, with customer-site routers named under
as8990.net.
Notable
- Mixed-use ISP space. The bulk of what resolves is end-user access, but a meaningful share is downstream-ISP and business-customer addressing, so an individual address here can be either.
- All of the space is registered directly to the operator (
AHRT-MNT), under netnames such asHU-IRISZ-(its long-running ISP brand) andAntenna-Hungaria-. It is a real, self-registered operator, not brokered address space.
Interesting
- Antenna Hungária's core business is terrestrial radio and TV transmission from a national tower network, and some of the sub-assignment records still describe customer sites located at its microwave stations.

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 1,773 prefixes, as published 2026-10-13. 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.
