Master Net

MASTER NET most consistently maps in public network datasets to Master Net Telecom LTDA (Brazil), an ISP/telecom operator. Public records also show the company name tied to a Brazilian corporate identifier (CNPJ), but open sources mix nearby variants, so some corporate details remain fragmented.

Multiple independent sources associate the operator with ASN AS53223 and the IRR set AS-MASTERNETRS, and show IPv4/IPv6 allocations under that network. PeeringDB lists presence at IX.br Porto Alegre with published peering IPs, indicating active interconnection metadata.

Public, user-written reviews are sparse and scattered under similar names, making it hard to derive a stable sentiment trend. With limited verifiable review volume, the reputation signal looks neutral/unclear overall.
