Summary
P&K Telecom
isp cable dsl regional
AS28238 is operated by Sator Engenharia Ltda., also known as P&K Telecom.
What it's used for
- The space carries residential and small business access traffic, consistent with the operator's classification as a Cable/DSL/ISP.
- The network announces 4096 IPv4 addresses within a single /20 prefix (187.0.128.0/20) and maintains 5 observed neighbours, a ratio indicative of a regional access provider rather than a transit hub.
Notable
- The RDAP registrant for the announced prefix is Sator Engenharia Ltda., which matches the AS holder.
- The operator is also identified in peering databases as P&K Telecom, suggesting a rebrand or dual identity for the same entity.
- The address inventory consists of a single contiguous /20 block in Brazil, with no IPv6 prefixes announced.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
