isp residential poland telecom

TELNET-KR-AS is operated by Telnet Sp. z o.o.

What it's used for

  • The address space carries residential and business access traffic, evidenced by the reverse DNS entry czarodziejska.telnet.krakow.pl and the netname TELNET.
  • The AS announces 1024 IPv4 addresses across 1 prefix (91.196.212.0/22) with 1 observed neighbour, indicating a local access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs and local business connections for Telnet's wired telecommunications services in Kraków.

Notable

  • The RDAP registrant TELNET Sp. z o.o. matches the AS holder, confirming consistent ownership of the address space.
  • The inventory is a single contiguous /22 block, typical for a regional ISP managing a dedicated address estate.

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 1,772 prefixes, as published 2026-10-15. 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.
