About this network

PDDA-AS is operated by Prometeus (CDLAN SpA).

What it's used for

• The address space carries a mix of ISP and cloud infrastructure, evidenced by netnames such as IT-ISPCDLAN-20120418, CLOUD-IAAS-1, and VIRTUALIZATION-CLUSTER-3.
• With 8960 IPv4 addresses announced across 15 prefixes and 25 observed neighbours, the ratio suggests a regional access provider with some hosting or cloud capabilities rather than a pure transit carrier.

Notable

• Registrants are split between CDLAN SpA and Iperweb Ltd, with Iperweb Ltd holding several cloud and virtualization blocks like CLOUD-PM-1 and Prometeus.
• The address inventory is finely subdivided into multiple /24 and /23 blocks, indicating site-by-site or service-specific segmentation within the corporate estate.
