About this network
SIEMENS-PLM is the autonomous system for Siemens Corporation.
What it's used for
- The address space carries corporate infrastructure, evidenced by the consistent netname SIEMENS-AG across all registrant entries.
- The AS announces 4352 IPv4 addresses across 12 prefixes and 2 IPv6 prefixes, maintaining 10 observed neighbours. This ratio of a finely subdivided address inventory against a moderate number of peers indicates an internal corporate estate with site-by-site segmentation rather than a transit or access network.
Notable
- All registrants align with the announcer, with every prefix registered to Siemens Corporation under the netname SIEMENS-AG.
- The address inventory is fragmented into numerous /24 and /23 blocks, primarily within the 134.244.0.0/16 and 146.122.0.0/16 ranges, reflecting a distributed internal network structure.
