business gas tso slovakia

EUSTREAM-AS is held by Eustream, a.s.

What it's used for

  • The address space carries corporate infrastructure for a natural gas transmission system operator, as indicated by the netname EUSTREAM and registrant BENESTRA RIPE ADMINISTRATOR; eustream as.
  • The AS announces a single IPv4 prefix (91.223.173.0/24) comprising 256 addresses with one observed neighbour, a ratio consistent with a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal systems for the Slovak gas transmission network operator, including administrative and operational endpoints.

Notable

  • The registrant BENESTRA RIPE ADMINISTRATOR; eustream as aligns with the announcer EUSTREAM-AS, confirming the identity of the holder.
  • Eustream, a.s. is the operator of the natural gas transmission network in the Slovak Republic, ensuring safe and reliable transport of gas to European markets.
  • The address inventory is minimal, consisting of a single /24 block, which fits the profile of a specialized utility company with limited public-facing internet presence.

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 1,771 prefixes, as published 2026-10-15. 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.
