AS52772 SJNET TELECOMUNICACOES - EIRELI
Unclassified RIPE Route Server
Summary
Sjnet Telecom
isp residential brazil
AS52772 is operated by Sjnet Telecomunicações - EIRELI.
What it's used for
- The address space carries residential broadband traffic, evidenced by the reverse DNS record
177-39-158-254.sjnettelecom.com.brand the netname190393associated with the registrant. - The AS announces 1024 IPv4 addresses across a single /22 prefix and 9 IPv6 prefixes, while maintaining 52 observed neighbours; this ratio of modest address inventory against a high neighbour count indicates a transit or peering-heavy role for a regional carrier.
- As a telecommunications provider in Brazil, the traffic consists of subscriber internet access, including web browsing, streaming, and VoIP services for its customer base.
Notable
- The RDAP registrant
SJNET TELECOMUNICACOES - EIRELImatches the AS holder name exactly, confirming consistent ownership of the announced space. - The inventory is compact, consisting of one contiguous IPv4 block and a set of hierarchical IPv6 prefixes, typical of a focused regional ISP rather than a large national carrier.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
