About this network

PLANISWARE is operated by Planisware SA.

What it's used for

• The space carries corporate infrastructure for Planisware, a French SaaS provider of cloud-based business planning and performance management software.
• The AS announces 1024 IPv4 addresses across 2 prefixes and 3 IPv6 prefixes, with 82 observed neighbours. This ratio of modest address space to high peering density indicates a corporate network with significant external connectivity requirements rather than a transit or access provider.
• Traffic from this AS consists of internal corporate communications, access to Planisware's cloud services, and business operations for its employees and data centers.

Notable

• Registrants for both announced IPv4 prefixes are listed as Planisware SA, matching the AS holder and confirming direct ownership of the address space.
• Planisware SA is a publicly traded company (PLNW:PAR) that began preparing for an IPO in 2023, with prior investment from the private equity firm Ardian.
• The address inventory is compact, consisting of two contiguous /23 blocks in the 185.204.120.0 range and three IPv6 /31 and /30 prefixes, typical of a single-tenant corporate estate.
