Residential APNIC Cable/DSL/ISP
Summary
Giga+ Fibra
isp residential fiber brazil
AS28210 is operated by Giga+ Fibra Telecomunicações S.A., a Brazilian broadband provider.
What it's used for
- The address space carries residential and business fiber connections, evidenced by reverse DNS records pointing to
static.sumicity.net.br. - The AS announces 56,320 IPv4 addresses across 38 prefixes and 24 IPv6 prefixes, while maintaining 41 observed neighbours, a ratio consistent with an access network serving end-users rather than a transit provider.
Notable
- All sampled registrants for the largest prefixes are listed as
GIGA MAIS FIBRA TELECOMUNICACOES S.A., matching the AS holder. - The operator is also known as Sumicity, a name reflected in the reverse DNS infrastructure.
- The inventory consists of a mix of /19, /20, /21, and /22 blocks, indicating a finely subdivided address estate typical of a regional ISP managing multiple service areas.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
8 upstream, 24 downstream and 51 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
