Brazil · AI-generated

isp residential cable dsl

AS28305 is operated by Persis Internet LTDA, a regional internet service provider in Brazil.

What it's used for

  • The address space carries residential and small-business access traffic, evidenced by reverse DNS entries such as acesso-148-0.persisinternet.com.br and rede-98.persisinternet.com.br.
  • The AS announces 9,216 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 27 observed neighbours; this ratio of moderate address space against a significant number of peers suggests a regional access provider with multiple upstream or peering relationships.

Notable

  • Registrants for the majority of prefixes are PERSIS INTERNET LTDA, though the 209.14.236.0/22 block is registered to LGTEL61 Internet LTDA, which PeeringDB identifies as an alias for Persis Internet.
  • The address inventory consists of four blocks in the 189.39.0.0/16 and 189.85.0.0/16 ranges, plus one block in 209.14.0.0/16, indicating a consolidated regional footprint.

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 1,773 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.
