Summary
Bi-Link Telecom
isp residential brazil access
Bi-Link Telecom is the AS handle for Bi-Link Telecom.
What it's used for
- The address space carries residential and business subscriber traffic, evidenced by reverse DNS records pointing to
bilink.com.br(e.g.,177-221-98-0.bilink.com.br). - The AS announces 4,096 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 14 observed neighbours; this ratio indicates an access network providing last-mile connectivity rather than a transit provider.
- Traffic from this AS consists of end-user internet access, including web browsing, streaming, and VoIP, typical of a regional Brazilian ISP.
Notable
- All available RDAP registrants for the announced prefixes list
Bi-Link Telecomas the holder, matching the AS name. - The address inventory is concentrated in the
177.221.96.0/21and177.221.108.0/22blocks, with smaller /23 and /24 allocations, reflecting a standard ISP address plan.

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 1,773 prefixes, as published 2026-10-13. 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.
