About this network

The AS handle ELBRACHT-COMPUTER-AS is held by Elbracht-Computer Netzwerk & Grafik Service GmbH.

What it's used for

• The address space carries internal corporate infrastructure, evidenced by the reverse DNS record cus254-als.elbracht.net pointing to the company's own domain.
• The network announces a single IPv4 prefix, 217.73.144.0/21, comprising 2048 addresses, against 16 observed neighbours. This ratio of a small, single-block inventory to a moderate number of peers suggests a small business or enterprise network rather than a large transit or access provider.

Notable

• The RDAP registrant for the announced prefix is listed as unknown with the netname RIPE-NCC-MANAGED-ADDRESS-BLOCK, which does not explicitly match the AS holder name in the registry, though the reverse DNS confirms the space is used by Elbracht.
• The address inventory consists of a single contiguous /21 block with no IPv6 prefixes announced, indicating a focused IPv4-only deployment.
