SINTNET-TELECOMUNICACOES E INFORMATICA LTDA

SINTNET-TELECOMUNICACOES E INFORMATICA LTDA appears in public ASN/WHOIS data as a Brazilian ISP organization, associated with AS61751 (LACNIC allocation date shown as 2014-08-12). Public registry extracts list “alexandre moraes” as the responsible contact for the ASN, but broader corporate/service details are limited in the sources reviewed.

The company operates AS61751 and announces IPv4 space including 131.72.252.0/22 and 168.228.40.0/22, plus IPv6 space under 2804:1bcc::/32; third-party datasets place parts of this footprint in Rio de Janeiro state (e.g., Nova Iguaçu and Queimados). Multiple ASN intelligence sources list upstream connectivity that includes Hurricane Electric (AS6939), Level 3/Lumen (AS3356), and Brazilian providers such as FORTE TELECOM (AS263009) and CX Pro (AS267470), indicating standard BGP transit relationships.

Clear, consistent end-user review coverage for this specific legal entity is scarce in the openly indexed sources checked, so a reputation score cannot be grounded in a meaningful volume of customer feedback. Some security/fraud-scoring pages characterize individual IPs in this ASN as low risk, but that is not a substitute for service reviews.
