AS28137 is operated by Vialink Solucoes de Tecnologia Ltda.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries like 255-167-45-187.vialink.com.br and 254-171-45-187.vialink.com.br.
  • The AS announces 4096 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with 13 observed neighbours. This ratio of address space to peering partners is consistent with an access provider rather than a transit carrier.

Notable

  • The RDAP registrant Vialink Soluções de Tecnologia Ltda matches the AS holder name, confirming consistent ownership of the announced space.
  • The inventory consists of a single contiguous IPv4 block, 187.45.160.0/20, and a single IPv6 prefix, 2804:458::/32, indicating a focused and compact address estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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 1,778 prefixes, as published 2026-10-20. 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.
