Summary

Pe3ny Net s.r.o.

Czechia · AI-generated

isp residential czech small

ACVYSKOV-AS is operated by Pe3ny Net s.r.o., a Czech internet service provider based in Prague.

What it's used for

  • The address space carries residential and small-business internet access, evidenced by the reverse DNS record gw.jkkatisk.cz and netnames CZ-PE3NY-20081118 and CZ-PE3NY-20151218 registered to the operator's NOC.
  • The AS announces 3,072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed upstream neighbour, indicating a small access network that purchases transit rather than providing it.
  • Traffic from this AS consists of subscriber internet access for residential and local business customers in the Czech Republic.

Notable

  • Both announced IPv4 prefixes are registered to Pe3ny Net s.r.o. with netnames matching the operator, confirming consistent ownership.
  • The address inventory is compact, comprising two IPv4 blocks (94.199.192.0/21 and 185.131.244.0/22) and one IPv6 /32, typical of a regional Czech ISP.

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.
