isp residential regional brazil

The AS handle SOBRALNET SERVICOS E TELECOMUNICACOES LTDA - ME is held by Sobralnet.

What it's used for

  • The address space carries residential and small business internet access, consistent with the operator's identity as a regional cable/DSL ISP.
  • The AS announces 24,576 IPv4 addresses across 16 prefixes and 17 IPv6 prefixes, while maintaining 185 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a regional access provider rather than a transit carrier.

Notable

  • All registrants in the RDAP sample match the announcer, consistently listing SOBRALNET SERVICOS E TELECOMUNICACOES LTDA - ME.
  • The address inventory is finely subdivided, with multiple /22, /23, and /24 blocks within the 186.225.32.0/20 range, suggesting site-by-site or customer-segment allocation typical of a local ISP.

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: 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.
