About this network

GMG is operated by GMG AG.

What it's used for

• The address space carries corporate infrastructure for GMG, evidenced by netnames such as LI-GMG-NET-20190516, GMG-NET, and CH-GMG-YM.
• The AS announces 5120 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining 51 observed neighbours; this ratio of moderate address space against a high neighbour count suggests a business network with significant peering or transit relationships rather than a pure access provider.

Notable

• Registrants are consistent with the announcer, primarily listing GMG AG, with one prefix (91.224.94.0/23) also listing GMG GmbH and TON AG.
• The address inventory is finely subdivided into multiple /23 and /24 blocks, indicating site-by-site segmentation typical of an internal corporate estate.
