Czechia · AI-generated

individual residential czechia small

The AS handle HNOJNIK is held by Pavel Jochim.

What it's used for

  • The space carries a single IPv4 block 185.158.64.0/22 and one IPv6 prefix 2a07:aa80::/29, with the netname CZ-HNOJNIK-20160701 registered to Pavel Jochim.
  • The inventory consists of 1024 IPv4 addresses and 1 IPv6 prefix, observed against 1 neighbour, indicating a small, self-contained network rather than a transit or large access provider.

  • The address inventory is a single contiguous /22 block, typical of a small personal or local allocation.

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.
