Summary
Giga+ Fibra
mobile residential telecom brazil
AS28598 is operated by DB3 SERVICOS DE TELECOMUNICACOES S.A, also known as Giga+ Fibra or Mob Telecom.
What it's used for
- The address space carries mobile and dynamic residential traffic, evidenced by reverse DNS entries such as
187-120-52-0.mobtelecom.com.br,201-20-68-0.dynamic.mobtelecom.com.br, and201-20-82-0.mobile.mobtelecom.com.br. - The AS announces 45,568 IPv4 addresses across 43 prefixes and 43 IPv6 prefixes, while maintaining 151 observed neighbours; this high neighbour count relative to the address inventory indicates a transit or peering-heavy role typical of a regional telecom provider.
Notable

DB3 SERVICOS DE TELECOMUNICACOES S.A, consistent with the AS holder. - The operator is identified in secondary sources as Giga+ Fibra (aka Mob Telecom), a telecommunications service provider in South America.
- The inventory consists of a mix of /20, /21, and /22 IPv4 blocks, with a significant portion of the space allocated to the
201.20.0.0/16range.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
