Brazil · AI-generated

isp residential brazil nsp

AS28589 is operated by Convex Internet Solutions.

What it's used for

  • The address space carries residential and business internet access, evidenced by the reverse DNS record cnp-187-254.static-rpo.convex.com.br which indicates static IP allocation for customer premises.
  • The network announces 4096 IPv4 addresses within a single /20 prefix and 27 IPv6 prefixes, while maintaining only 1 observed neighbour. This high address-to-neighbour ratio is characteristic of an access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant for the announced block 200.152.176.0/20 is listed as Convex Internet Solutions with netname 50251, which aligns directly with the AS holder name.
  • The address inventory consists of one contiguous IPv4 block and a fragmented set of IPv6 prefixes under the 2804:998::/47 space, suggesting internal segmentation for different service tiers or geographic regions.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-23, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
