Summary

ComUnited

Czechia · AI-generated

isp residential czech

The AS handle COMUNITED is held by Jan Saulich.

What it's used for

  • The address space carries residential or small business internet access, evidenced by the reverse DNS record gw-254.comunited.cz and the netname COMUNITED.
  • The network announces 2048 IPv4 addresses within a single /21 prefix (178.216.80.0/21) and maintains only 1 observed neighbour, a ratio characteristic of a local access provider rather than a transit carrier.
  • Traffic from this AS consists of end-user internet access for subscribers in the Czech Republic.

Notable

  • The RDAP registrant Jan Saulich matches the registry holder and the AS handle, indicating direct ownership of the address space.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, 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: 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.
