isp residential brazil cable

AS28591 is operated by Metro Telecomunicações S/A.

What it's used for

  • The address space carries residential and business connectivity, evidenced by the reverse DNS record c1026.cloud.metrotelecom.com.br and the registrant netnames 187384 and 51176.
  • The AS announces 6144 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a local access network rather than a transit provider.

Notable

  • All RDAP registrants for the announced prefixes are listed as METRO TELECOMUNICAÇÕES S/A, matching the AS holder name.
  • The address inventory consists of a single /21 block in the 177.55.0.0/16 range and four blocks in the 200.142.0.0/16 range, reflecting 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: 440 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.
