About this network

Silica Networks Argentina S.A. is the Argentine arm of Silica Networks, a Grupo Datco company that builds and sells long-haul fibre capacity and IP transit across Argentina and Chile.

What it's used for

• Wholesale connectivity: fibre transport, IP transit and capacity sold to other carriers, ISPs and large enterprises rather than to households.
• Reverse DNS on the announced prefixes is uniformly …static.silicanetworks.com, statically assigned customer address space with no dynamic subscriber pools of the kind an eyeball ISP produces.

Notable

• Silica operates a DWDM long-haul network crossing the Andes between Argentina and Chile, with onward reach toward Brazil and Uruguay, which is what puts it in the carrier's-carrier tier rather than the retail one.
• The company expanded its Argentine footprint by taking over InterNexa's wholesale fibre operation in the country.
