Czechia · AI-generated

isp residential czech small

JARONET-AS is operated by JaroNet-services s.r.o.

What it's used for

  • The address space carries residential internet services in the Czech Republic, as indicated by the netnames CZ-JARONET-SERVICES-20101227 and CZ-JARONET-SERVICES-20200731 and the registrant JaroNet-services s.r.o.
  • The AS announces 4,352 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 1 observed neighbour, indicating a small access network rather than a transit provider
  • Traffic from this AS consists of subscriber eyeballs for residential broadband users in the Czech Republic, consistent with the operator's role as a local ISP

Notable

  • Registrants for both announced prefixes match the AS holder, JaroNet-services s.r.o., confirming consistent ownership
  • The address inventory is compact, consisting of one /20 block (46.252.224.0/20) and one /24 block (185.168.140.0/24), typical of a small regional ISP

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
