Summary

GYSEV Zrt.

Hungary · AI-generated

railway business hungary

GYSEV-AS is operated by GYSEV Zrt., a Hungarian railway company.

What it's used for

  • The address space carries corporate infrastructure for the GYSEV railway group, as indicated by the netname GYSEV and the registrant Magyar Telekom RIPE Administrator.
  • The AS announces 256 IPv4 addresses within a single prefix (195.228.58.0/24) and maintains 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications, office systems, and operational endpoints for the railway operator's business activities.

Notable

  • The registrant Magyar Telekom RIPE Administrator differs from the AS holder GYSEV Zrt., suggesting the address space is leased or managed through Magyar Telekom's RIPE services.
  • GYSEV Zrt. is a long-established railway operator in Hungary and Austria, incorporated in 1876, operating passenger and freight services across the region.
  • The inventory consists of a single /24 block with no IPv6 prefixes, reflecting a minimal and static address footprint typical of a private corporate network.

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: 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.
