Summary

PROFZONE

Switzerland · AI-generated

business switzerland single-prefix

The AS handle PROFZONE is held by Erich Hohermuth.

What it's used for

  • The address space carries a single /24 block (195.8.113.0/24) with reverse DNS entries pointing to the hoh.ch domain, indicating a small-scale private or corporate network.
  • With 256 IPv4 addresses announced against only 1 observed neighbour, the ratio suggests a stub or end-site network rather than a transit provider.

Notable

  • The RDAP registrant for the sole prefix is Erich Hohermuth, which aligns directly with the registry holder name.
  • The inventory consists of a single contiguous IPv4 prefix with no IPv6 announcements, representing a minimal and static address footprint.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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 1,772 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.
