What it's used for

• The address space carries the network infrastructure for the Płock branch of the Warsaw University of Technology, identified by the netname PWPLOCK.
• The AS announces 512 IPv4 addresses within a single prefix (148.81.246.0/23) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.
• Traffic from this AS consists of academic and administrative endpoints for the university's Płock campus, including student and staff devices connected to the local campus network.

Notable

• The RDAP registrant for the announced prefix is NASK LIR, which is the Polish Internet Registry, while the AS holder is the university itself; this reflects the standard allocation of address space by the national registry to the end-user institution.
• The inventory consists of a single contiguous /23 block, indicating a compact and unified address allocation for the branch.
