AS28343 currently announces 185 IPv4 block(s), totaling about 343.8 thousand addresses (343,808 in all), registered in Brazil. Services from UNIFIQUE TELECOMUNICACOES SA are reached through these addresses.

What it means to see AS28343 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS28343. That means the other end sits on the UNIFIQUE TELECOMUNICACOES SA network (Brazil). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
