What it's used for

• The address space carries internal corporate infrastructure, evidenced by reverse DNS entries like host-185-088-061-000.nh.zone and netnames DE-NERDHERRSCHAFT-20101116 and DE-NERDHERRSCHAFT-20150216.
• The AS announces 3072 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
• Traffic from this AS consists of office workers and R&D staff accessing the internet, as Nerdherrschaft is a German company providing custom hardware and software R&D services and IT consulting.

Notable

• Registrants for both prefixes are listed as "Nerdherrschaft Network Operations; Nerdherrschaft GmbH", which aligns directly with the AS holder.
• The address inventory is small and finely subdivided into two distinct blocks, consistent with an internal corporate estate segmented by site or function.
