Unclassified ARIN NSP
Summary
Bahialink Technology
isp residential brazil access
AS61902 is operated by Bahialink Technology Ltda.
What it's used for
- The address space carries residential and dynamic subscriber traffic, evidenced by reverse DNS entries such as
dinamico.bahialink.net.brandnetmundbrasil.com.br. - The network announces 3072 IPv4 addresses across 3 prefixes and 26 IPv6 prefixes, while maintaining only 3 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.
- Traffic from this AS consists of end-user internet access for subscribers in Brazil, consistent with the operator's role as a regional internet service provider.
Notable
- All registrants for the announced prefixes are listed as Bahialink Technology Ltda, matching the AS holder.
- The address inventory is compact, consisting of three /22 IPv4 blocks and a single /40 IPv6 allocation subdivided into smaller prefixes.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, 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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
