residential isp cable regional

TOYA-KRAKOW-AS is operated by City Partner Sp. z o.o., a regional cable and DSL internet service provider in Poland.

What it's used for

  • The address space carries residential subscriber traffic, as indicated by the reverse DNS record 128.60.citypartner.pl and the netname PL-TOYA-KRAKOW.
  • The AS announces 512 IPv4 addresses within a single prefix (195.210.60.0/23) and maintains 2 observed routing neighbours, a ratio consistent with a regional access network rather than a transit provider.
  • Traffic from this AS consists of end-user internet access for residential customers in the Krakow region, delivered via cable and DSL infrastructure.

Notable

  • The RDAP registrant Toya sp.z.o.o and the netname PL-TOYA-KRAKOW align with the AS holder, while the reverse DNS and PeeringDB identify the operational brand as City Partner.
  • The address inventory is compact, consisting of a single /23 block, which is typical for a regional ISP serving a specific local market.

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 1,781 prefixes, as published 2026-10-16. 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.
