About this network

PSC is the autonomous system for Progress Software.

What it's used for

• The address space carries corporate infrastructure, evidenced by the netname PSCNET registered to Progress Software.
• The AS announces 1024 IPv4 addresses across 2 prefixes with 3 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.

Notable

• Registrants do not fully agree with the announcer; one prefix is registered to Zayo Bandwidth with netname ZAYO-CCF-131-239-0-0, while the other is registered to Progress Software.
• The address inventory is small and finely subdivided into two /23 blocks, indicating site-by-site segmentation for a single corporation.
