Summary
Sglinknet Telecomunicacoes
isp brazil telecom
AS52903 is operated by Sglinknet Telecomunicacoes Ltda-ME.
What it's used for
- The address space carries residential and small business connectivity, evidenced by the reverse DNS record
177-11-171-255.deepconnect.net.brwhich indicates a dynamic access network. - The AS announces 2304 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, maintaining 7 observed neighbours; this ratio of address space to peering partners is consistent with a local access provider rather than a transit hub.
- Traffic from this AS consists of subscriber eyeballs and small office internet access within Brazil.
Notable
- Registrants for the announced prefixes are mixed:
177.11.168.0/21is registered to Sglinknet Telecomunicacoes Ltda-ME, while187.62.253.0/24is registered to METROFLEX TELECOMUNICACOES LTDA, suggesting a lease or historical acquisition of that specific block. - The inventory is compact, consisting of one /21 and one /24 in IPv4, with the IPv6 space allocated in two distinct prefixes.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
7 upstream, 0 downstream and 8 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, 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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
