The AS handle AS28640 is held by VIPWAY Telecomunicacoes Ltda.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to vipway.net.br and linkfort.com.br.
  • The network announces 11,776 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, while maintaining 41 observed neighbours. This ratio of moderate address space against a high number of peering partners suggests a regional access provider with significant transit requirements.

Notable

  • All registrants for the announced prefixes are listed as VIPWAY Telecomunicações Ltda, consistent with the AS holder.
  • The address inventory is concentrated in the 189.51.0.0/16 range, with specific blocks like 189.51.64.0/20 and 189.51.80.0/21, alongside a separate block at 201.71.224.0/20.
  • The reverse DNS sample shows a mix of vipway.net.br and linkfort.com.br domains, indicating potential infrastructure consolidation or shared DNS management.

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 1,783 prefixes, as published 2026-10-17. 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.
