Summary

isp residential czech

COMANET-NETWORK is operated by Ing. Leos Janouch.

What it's used for

  • The address space carries residential broadband traffic, evidenced by the reverse DNS record nat-pool-254.comanet.cz and the netname COMANET-NET.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for a local Czech internet service provider.

Notable

  • The RDAP registrant Ing. Leos Janouch matches the registry holder, confirming consistent ownership.
  • The inventory consists of a single /22 block (91.218.188.0/22) and a single /48 IPv6 prefix, representing a compact, single-site address estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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 1,779 prefixes, as published 2026-10-21. 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.
