About this network

The AS handle NETDESIGN-ZONE is held by networkers.pl Sp. z o.o.

What it's used for

• The space carries addresses with reverse DNS names like numerek-64.wtakiejsobiezajefajnejsieci, indicating a small, informal network environment.
• The AS announces 256 IPv4 addresses across 1 prefix (217.17.37.0/24) and has 1 observed neighbour, a ratio consistent with a small-scale or research network rather than a transit or large access provider.
• PeeringDB classifies the operator as Educational/Research, and the associated website and GitHub repository suggest a focus on network design and experimentation.

Notable

• The RDAP registrant for the announced prefix is listed as ATMAN NOC, which differs from the AS holder networkers.pl Sp. z o.o., suggesting the address space may be leased or managed by a different entity.
• The address inventory consists of a single /24 block, indicating a compact and limited scope of operation.
