Summary

Opton s.r.o.

Czechia · AI-generated

business czech small

The AS handle ASOPTON is held by Opton s.r.o.

What it's used for

  • The address space carries the netname OPTON registered to Opton s.r.o., indicating a single-tenant corporate allocation.
  • The network announces 1024 IPv4 addresses across 1 prefix (176.124.184.0/22) with 0 IPv6 prefixes, and observes 1 routing neighbour.
  • This low neighbour count against a small, single-prefix inventory indicates a direct peering or transit relationship for a specific business site rather than a large-scale access or transit provider.

Notable

  • The RDAP registrant Opton s.r.o. matches the AS holder, confirming consistent ownership of the address space.
  • The inventory consists of a single /22 block, representing a compact and self-contained address allocation.

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.

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.
