AS53213 is operated by BLV TECNOLOGIA LTDA.

What it's used for

  • The address space carries broadband access traffic, as indicated by the AS handle NEGRISOLO COMUNICACAO BANDA LARGA LTDA ME and the registrant BLV TECNOLOGIA LTDA for both announced IPv4 prefixes.
  • The network announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber broadband connections, consistent with the operator's business in communication and broadband services.

Notable

  • The RDAP registrants for both the 186.250.64.0/21 and 177.85.228.0/22 prefixes are BLV TECNOLOGIA LTDA, which aligns with the registry holder.
  • The address inventory is composed of two distinct IPv4 blocks and a single IPv6 /32, with all announced blocks located in Brazil.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-06, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
