hosting business switzerland

The AS handle HOSTEUR-NET-CORE-CH is held by Hosteur SA.

What it's used for

  • The address space carries hosting and business infrastructure, evidenced by netnames NET-BRAINSERVE-01, FR-HOSTEUR-20101118, and WAN-HOSTEUR-CH-ANYCAST.
  • The AS announces 2304 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with 3 observed neighbours, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web/API endpoints and hosted services for business clients, consistent with Hosteur's role as a Swiss hosting provider.

Notable

  • Registrants include Abuse-C Role and Hosteur SAS, with ABCONNECT Technical Contact listed for the FR-HOSTEUR-20101118 block, suggesting a mix of direct ownership and technical management.
  • The address inventory is compact, with three IPv4 prefixes totaling 2304 addresses and a single IPv6 prefix, reflecting a focused hosting operation.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
