Summary

SigmaNet

Hungary · AI-generated

hosting business hungary

SIGMANET-HU-AS is operated by SigmaNet Szolgaltato es Kereskedelm Ltd.

What it's used for

  • The address space carries hosting and business infrastructure, evidenced by reverse DNS entries such as shost-57E56280.sigmanet.hu, vps-57e5667f.sigmanet.hu, and smtp.rendszer-uzemeltetes.hu.
  • The AS announces 2560 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web/API endpoints, VPS instances, and mail servers for Hungarian businesses and individuals.

Notable

  • Registrants for the majority of prefixes are listed as "Abuse Contact" with netnames SIGMANET or TAURI-NET, consistent with the announcer SigmaNet.
  • The address inventory is finely subdivided into /24 blocks, with one /23, suggesting site-by-site or customer-segmented allocation typical of a small hosting provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
