Summary
Telecentro
residential isp cable dsl
The AS handle Telecentro S.A. is operated by Telecentro, a regional cable and DSL provider in Argentina.
What it's used for
- The address space carries residential customer endpoints, evidenced by reverse DNS entries like
cpe-186-18-64-0.telecentro-reversos.com.arand netnames explicitly labeled "Clientes Residenciales". - With 623,104 IPv4 addresses announced across 141 prefixes and only 13 observed neighbours, the high address-to-neighbour ratio indicates an access network serving end-users rather than a transit provider.
Notable
- All registrants in the RDAP sample are listed as Telecentro S.A., matching the AS holder and confirming consistent ownership of the announced space.
- The inventory is dominated by large blocks in the 181.44.0.0/16 and 186.18.0.0/16 ranges, with 181 prefixes announced in Argentina, reflecting a substantial domestic footprint.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
