Summary

Giga+ Fibra

Brazil · AI-generated

residential isp fiber brazil

AS28294 is operated by Giga+ Fibra Telecomunicações S.A., a Brazilian fixed-line internet service provider.

What it's used for

  • The address space carries residential and business fiber access, evidenced by reverse DNS entries such as 11-221-177-254.unitelecom.com.br and Lo0-rt000021.bras.uvxgpe-dc.univox.com.br.
  • The AS announces 27,136 IPv4 addresses across 19 prefixes and 6 IPv6 prefixes, while maintaining 15 observed neighbours; this high address-to-neighbour ratio indicates an access network rather than a transit provider.

Notable

  • All RDAP registrants for the largest prefixes are listed as GIGA MAIS FIBRA TELECOMUNICACOES S.A., consistent with the AS holder.
  • The operator is also known as Univox, a name reflected in the univox.com.br reverse DNS records.
  • The inventory consists of a mix of /20, /21, /22, /23, and /24 blocks, with the largest being 177.221.0.0/20 and 179.107.192.0/20.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 432 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.
