About this network

PFALZKOM is the autonomous system for Pfalzkom GmbH, a German telecommunications provider based in Mannheim.

What it's used for

• The address space carries customer access traffic, evidenced by reverse DNS entries like 212-65-23-254.cust.pfalzkom.net and netnames such as DE-MANET-981027 and DE-PFALZKOM-20000406.
• With 45312 IPv4 addresses announced across 31 prefixes and 157 observed neighbours, the ratio indicates a regional access network providing connectivity to end-users and businesses rather than a pure transit provider.

Notable

• Registrants largely align with the announcer, including Pfalzkom Network Operations and PFALZKOM GmbH, though some prefixes are registered to third parties like Grosskraftwerk Mannheim AG and Tegro Kabelbau GmbH, suggesting leased space or historical acquisitions.
• The inventory includes a mix of large /19 blocks and smaller /22 and /24 prefixes, reflecting a diverse customer base ranging from enterprise clients to residential subscribers.
