Summary
Newcenter Telecom
isp residential cable regional
NEWCENTER TELECOM is the AS handle for Newcenter Telecom, a regional ISP operating in Brazil.
What it's used for
- The address space carries dynamic subscriber traffic, evidenced by reverse DNS entries such as
170-83-93-0.dinamico.newcentertelecom.com.brand177-72-29-0.dinamico.newcentertelecom.com.br. - The network announces 3,072 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 27 observed neighbours; this ratio indicates an access network providing last-mile connectivity rather than transit.
- Traffic from this AS consists of residential and small business subscriber eyeballs, consistent with the operator's classification as a Cable/DSL/ISP provider.
Notable
- All registrants for the announced prefixes (
170.83.92.0/22,177.72.28.0/22,179.124.204.0/22) are listed as NEWCENTER TELECOM, matching the AS holder. - The inventory is composed of three contiguous /22 blocks in the IPv4 space and a single /32 in IPv6, reflecting a modest, regionally focused address estate.

Residential Fixed-line consumer ISP. Addresses here are homes.
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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
