Summary

Czechia · AI-generated

isp residential czech small

P12com is operated by Praha12.com s.r.o.

What it's used for

  • The address space carries residential and small business internet access, evidenced by the reverse DNS record unassigned.praha12.com and the netname CZ-PRAHA12COM-20191009.
  • The AS announces 1024 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 3 observed routing neighbours, indicating a small access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for local internet service in the Prague area, specifically Modřany.

Notable

  • Registrants for both announced IPv4 prefixes are Martin Vilimovsky and Praha12.com s.r.o., consistent with the AS holder.
  • Praha12.com s.r.o. is a subsidiary established to provide a full portfolio of communication services, as indicated by its corporate history.
  • The inventory is compact, consisting of two /23 blocks and a single /29 IPv6 prefix, typical of a local ISP.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-13, 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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
