Summary
PW Network
isp brazil residential
AS52876 is operated by PW Network Informatica E Telecomunicacoes Ltda.
What it's used for
- The address space is registered under the netname
179995for both announced IPv4 prefixes, indicating a single administrative entity. - The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 27 observed neighbours. This ratio of moderate address space to a significant number of peering partners suggests a regional access provider or small ISP rather than a large transit carrier.
- Traffic from this AS consists of subscriber eyeballs and local internet access services, consistent with the operator's business as a telecommunications and informatics company serving specific regions in Brazil.
Notable
- Registrants for both IPv4 prefixes match the AS holder, PW Network Informatica E Telecomunicacoes Ltda, confirming consistent ownership.
- The address inventory is compact, comprising two contiguous IPv4 blocks and one IPv6 /36, typical of a regional ISP managing local customer allocations.

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 2026-11-14. 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.
