About this network

CLARANET-PT is Claranet Portugal S.A., the Portuguese arm of the Claranet group, a European managed-services provider. It is one of the country's larger IT and hosting operators.

What it's used for

• Managed hosting, cloud, and managed-network services for business customers: dedicated and cloud servers, backup and disaster recovery, cyber-security services, and MPLS/VPN connectivity.
• Serving customer workloads out of Claranet's own Portuguese data centres in Lisbon and Porto.

Notable

• This is a hosting and managed-services network, not a consumer ISP. Addresses here belong to servers and business customer estates rather than home broadband lines.
• The footprint is substantial for a national managed-services provider, on the order of tens of thousands of IPv4 addresses.

Interesting

• Claranet began in 1996 as an internet service provider and grew into a managed IT services group across Europe and Brazil, which is why several of its country networks still sit on low, early-allocated AS numbers.
