About this network

REGISTER-AS is operated by Register.it S.p.A., a major Italian domain registrar and web hosting provider.

What it's used for

• The address space carries dedicated server and web application infrastructure, evidenced by reverse DNS entries such as host-81-88-62-254.dedicatedservers.it and khbk0001.webapps.net.
• The AS announces 11,264 IPv4 addresses across 16 prefixes and 1 IPv6 prefix, while maintaining 35 observed neighbours; this ratio indicates a hosting and business service provider rather than a transit carrier.
• Traffic from this AS consists of web hosting endpoints, dedicated servers, and domain registration services for business and consumer clients in Europe.

Notable

• Registrants align with the announcer, listing REGISTER S.P.A. and DADA NOC - sistemisti for the majority of prefixes, including netnames like IT-REGISTER-20060410 and IT-DADA-970904.
• The operator is the result of the merger between Register.it and Dada S.p.A., with Dada's historical address space (e.g., 195.110.120.0/21) now integrated into the unified Register.it infrastructure.
• The inventory is finely subdivided into 16 IPv4 prefixes, reflecting internal segmentation for different service lines or data center locations.
