About this network

MAYR-MELNHOF is operated by Mayr-Melnhof MM Service GmbH.

What it's used for

• The address space carries internal corporate IT infrastructure, evidenced by registrants MM IT NOC and netnames AT-MAYR-MELNHOF-20160330 and MAYRMELNHOF.
• The AS announces 1280 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
• Traffic from this AS consists of office workers, internal systems, and web/API endpoints for the Mayr-Melnhof group, a major European paper and packaging manufacturer.

Notable

• Registrants MM IT NOC and MM Service GmbH align with the announcer, confirming the space is owned and managed by the corporate IT department.
• The address inventory is finely subdivided into three distinct IPv4 blocks, consistent with site-by-site segmentation for a large industrial enterprise.
