Summary
Sitel
isp residential brazil cable
AS53102 is operated by S.I. Telecom. Servicos de Telefonica Ltda EPP, commonly known as Sitel.
What it's used for
- The address space carries residential and dynamic subscriber traffic, evidenced by reverse DNS entries such as
186-195-52-0.sitel.com.brand187-103-171-254.valido-dinamico.clicknet.com.br. - The AS announces 8,192 IPv4 addresses across 2 prefixes and 18 IPv6 prefixes, while maintaining 50 observed neighbours; this ratio of address space to peering partners indicates an access network serving end-users rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs for cable and DSL services in the Brazilian region, consistent with the operator's classification as a regional ISP.
Notable
- Registrants for both announced IPv4 prefixes (
186.195.48.0/20and187.103.160.0/20) match the AS holder, S.I. Telecom. Servicos de Telefonica Ltda EPP. - The address inventory is composed of two large /20 blocks in IPv4 and a fragmented set of ten IPv6 prefixes, reflecting a standard regional ISP allocation.

Classification and threat
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 1,781 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.
